But God is my King from the beginning. In this verse, as we have often seen to be the case in other places, the people of God intermingle meditations with their prayers, thereby to acquire renewed vigor to their faith, and to stir up themselves to greater earnestness in the duty of prayer. We know how difficult it is to rise above all doubts, and boldly to persevere in a free and unrestrained course of prayer. Here, then, the faithful call to remembrance the proofs of God's mercy and working, by which he certified, through a continued series of ages, that he was the King and Protector of the people whom he had chosen. By this example we are taught, that as it is not enough to pray with the lips unless we also pray in faith, we ought always to remember the benefits by which God has given a confirmation of his fatherly love towards us, and should regard them as so many testimonies of his electing love. It is quite clear that the title King, which is here applied to God, ought not to be restricted merely to his sovereignty. He is addressed by this appellation because he had taken upon him the government of the Jewish people, in order to preserve and maintain them in safety. We have already stated what is implied in the words, from the beginning. By the midst of the earth some think that Judea is intended, because it was situated as it were in the midst of the habitable globe. There is no doubt that it is to be understood of a place which stands prominently in view. We find the expression used in this sense in these words which God commanded Moses to speak to Pharaoh, "And I will sever in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end thou mayest know that I am the Lord in the midst of the earth," (Exodus 8:22.) The simple and natural meaning, therefore, is, that God had wrought in behalf of the chosen people many deliverances, which were as open and manifest as if they had been exhibited on a conspicuous theater.

For God is my King of old - That is, the king, or ruler of his people. The people had acknowledged him as their king and ruler, and he had showed himself to be such. This is given as a reason why he should now interpose in their behalf. It is an argument, proper always to be urged, drawn from the faithfulness and unchangeableness of God.
Working salvation in the midst of the earth - Salvation for his people. The reference here particularly is to what he had done for his people in delivering them from bondage in Egypt, and conducting them to the promised land, as is stated in the following verses.

For God is my King of old - We have always acknowledged thee as our sovereign; and thou hast reigned as a king in the midst of our land, dispensing salvation and deliverance from the center to every part of the circumference.

For God [is] my King of old, working salvation (h) in the midst of the earth.
(h) Meaning in the sight of all the world.

For God is my King of old,.... Or "but God", or "verily God", &c. (d); for these words contain the church's consolation under all the above melancholy circumstances, taken from what God was, and had been to her, even Christ, who is God over all; he was her King by the constitution and designation of his Father, and so he had been of old, even from everlasting; for so early was he set up as King; and he had in all ages been exercising his kingly office for the good of his church, and continued to do so; and this was her comfort, and is the comfort of saints in the worst of times, that Zion's King reigneth, see Psalm 46:1.
working salvation in the midst of the earth; it is "salvations" (e) in the plural number, and means both spiritual and eternal salvation, which the Lord has wrought out; and is continually applying to his people; and temporal salvation, which the Lord has been and is daily working out; he continually protecting his people, and saving them from their enemies, and delivering them out of their afflictions and temptations; and which the church considers and improves into an argument to encourage her faith, and expect the time when her walls would be salvation, and her gates praise; and she should have reason to say, now is come salvation and strength, and the kingdom of our God and the power of his Christ; and give him all the glory of it; see Isaiah 60:18, which salvation, as it has been, so will be wrought
in the midst of the earth; meaning not in the midst of the land of Judea, or in Judea, the middle of the world, but openly and publicly in all the earth; though Cyril of Jerusalem says (f) Golgotha is the midst of the earth, where Christ suffered and wrought out salvation; and that it is here referred to.

The church silences her own complaints. What God had done for his people, as their King of old, encouraged them to depend on him. It was the Lord's doing, none besides could do it. This providence was food to faith and hope, to support and encourage in difficulties. The God of Israel is the God of nature. He that is faithful to his covenant about the day and the night, will never cast off those whom he has chosen. We have as much reason to expect affliction, as to expect night and winter. But we have no more reason to despair of the return of comfort, than to despair of day and summer. And in the world above we shall have no more changes.

For--literally, "And," in an adversative sense.

With this prayer for the destruction of the enemies by God's interposition closes the first half of the Psalm, which has for its subject-matter the crying contradiction between the present state of things and God's relationship to Israel. The poet now draws comfort by looking back into the time when God as Israel's King unfolded the rich fulness of His salvation everywhere upon the earth, where Israel's existence was imperilled. בּקרב הארץ, not only within the circumference of the Holy Land, but, e.g., also within that of Egypt (Exodus 8:18-22). The poet has Egypt directly in his mind, for there now follows first of all a glance at the historical (Psalm 74:13-15), and then at the natural displays of God's power (Psalm 74:16, Psalm 74:17). Hengstenberg is of opinion that Psalm 74:13-15 also are to be understood in the latter sense, and appeals to Job 26:11-13. But just as Isaiah (Isaiah 51:9, cf. Psalm 27:1) transfers these emblems of the omnipotence of God in the natural world to His proofs of power in connection with the history of redemption which were exhibited in the case of a worldly power, so does the poet here also in Psalm 74:13-15. The תּנּיּן (the extended saurian) is in Isaiah, as in Ezekiel (התּנּים, Psalm 29:3; Psalm 32:2), an emblem of Pharaoh and of his kingdom; in like manner here the leviathan is the proper natural wonder of Egypt. As a water-snake or a crocodile, when it comes up with its head above the water, is killed by a powerful stroke, did God break the heads of the Egyptians, so that the sea cast up their dead bodies (Exodus 14:30). The ציּים, the dwellers in the steppe, to whom these became food, are not the Aethiopians (lxx, Jerome), or rather the Ichthyophagi (Bocahrt, Hengstenberg), who according to Agatharcides fed ἐκ τῶν ἐκριπτομένων εἰς τὴν χέρσον κητῶν, but were no cannibals, but the wild beasts of the desert, which are called עם, as in Proverbs 30:25. the ants and the rock-badgers. לציים is a permutative of the notion לעם, which was not completed: to a (singular) people, viz., to the wild animals of the steppe. Psalm 74:15 also still refers not to miracles of creation, but to miracles wrought in the course of the history of redemption; Psalm 74:15 refers to the giving of water out of the rock (Psalm 78:15), and Psalm 74:15 to the passage through the Jordan, which was miraculously dried up (הובשׁתּ, as in Joshua 2:10; Joshua 4:23; Joshua 5:1). The object מעין ונחל is intended as referring to the result: so that the water flowed out of the cleft after the manner of a fountain and a brook. נהרות are the several streams of the one Jordan; the attributive genitive איתן describe them as streams having an abundance that does not dry up, streams of perennial fulness. The God of Israel who has thus marvellously made Himself known in history is, however, the Creator and Lord of all created things. Day and night and the stars alike are His creatures. In close connection with the night, which is mentioned second, the moon, the מאור of the night, precedes the sun; cf. Psalm 8:4, where כּונן is the same as הכין in this passage. It is an error to render thus: bodies of light, and more particularly the sun; which would have made one expect מאורות before the specializing Waw. גּבוּלות are not merely the bounds of the land towards the sea, Jeremiah 5:22, but, according to Deuteronomy 32:8; Acts 17:26, even the boundaries of the land in themselves, that is to say, the natural boundaries of the inland country. קיץ וחרף are the two halves of the year: summer including spring (אביב), which begins in Nisan, the spring-month, about the time of the vernal equinox, and autumn including winter (צתו), after the termination of which the strictly spring vegetation begins (Song 2:11). The seasons are personified, and are called God's formations or works, as it were the angels of summer and of winter.

King - It belongs therefore to thy office to protect and save me. Midst - In the view of the world.
