He hath made known his ways to Moses David now speaks in the name of the chosen people; and this he does very suitably, being led to it by the consideration of the benefits which God had bestowed upon himself. Convinced that it was only as a member of the Church that he had been enriched with so many blessings, he immediately carries back his contemplations to the common covenant made with the people of Israel. He, however, continues the same train of thought as in the preceding verse; for these ways, which he says had been shown to Moses, were nothing else than the deliverance wrought for the people until they entered the promised land. He selected this as an instance of God's righteousness and judgment, surpassing all others, to prove that God always shows himself righteous in succoring those who are oppressed. But since this instance depended upon the Divine promise, he doubtless has an eye principally to it; his language implying that God's righteousness was clearly demonstrated and seen in the history of the chosen people, whom he had adopted, and with whom he had entered into covenant. God is said to have made known his ways first to Moses, who was his servant and messenger, and afterwards to all the people. Moses is here represented as invested with the office to which he was Divinely appointed; for it was God's will to be made known to the people by the hand and working of that distinguished man. The ways, then, and the doings of God, are his rising up with wonderful power to deliver the people, his leading them through the Red Sea, and his manifesting his presence with them by many signs and miracles. But as all this flowed from the free covenant, David exhorts himself and others to give thanks to God for having chosen them to be his peculiar people, and for enlightening their minds by the truths of his law. Man, without the knowledge of God, being the most miserable object that can be imagined, the discovery which God has been pleased to make to us in his Word, of his fatherly love, is an incomparable treasure of perfect happiness.

He made known his ways unto Moses - This is another ground of praise - that God had "revealed his will;" that this had been done in an indubitable manner to Moses; and that these revelations had been recorded by him for the instruction and guidance of his people. The word "ways" here means his laws; his methods of administration; the principles on which he governs mankind, and the conditions on which he will save people. There is no higher ground of gratitude to God than the fact that he has given a revelation to mankind.
His acts unto the children of Israel - His methods of doing things have been made known to them; and his acts - his interpositions - have been in their favor.

He made known his ways unto Moses - From the earliest part of our history he has been our protector and defense. His wonderful acts in behalf of the children of Israel are so many proofs of his mercy, power, and goodness; and so many reasons why we should now trust in him.

He made known his ways unto (e) Moses, his acts unto the children of Israel.
(e) As to his chief minister, and next to his people.

He made known his ways unto Moses,.... The ways in which he himself walks, the steps and methods which he has taken to show forth his glory; his way in creation, and the order of it, as in Genesis 1:1, for though, by the light of nature, it might be known that God created all things; yet, without a revelation from him, it could never have been known in what manner he made them, and the peculiar work of each of the six days, in which they were made; this was made known to Moses; as also his way in providence, which sometimes is in the deep, and past finding out: Moses was made acquainted with the methods of divine Providence, with many special instances of it, relating both to himself in his infancy and in riper years, and to the people of Israel in their march from Egypt to Canaan's land; and the Lord likewise made known unto him his way of grace and mercy, life and salvation, by Christ, which he desired to show him, and he did, Exodus 33:13. Christ was made known to him, as the seed of the woman that should break the serpent's head, as God's salvation, old Jacob waited for: he was shown him in the types of the passover lamb, the brasen serpent, and the rock in the wilderness, and in other things; the way of atonement, by the sacrifice of Christ, was made known to him through the sacrifices which he from God enjoined the people of Israel: hence he wrote of Christ, and of what he should do and suffer; and so fully, that the Apostle Paul said no other things than what he did, John 5:46 moreover, the Lord made known to him the ways in which he would have him and the people of Israel to walk; the way of his commandments, his statutes and ordinances; which were made known to him, to deliver to them, and was a peculiar favour, Psalm 147:19,
his acts unto the children of Israel; his works, his wonderful works; his plagues on their enemies the Egyptians; his redemption of them out of the house of bondage; his leading them through the Red sea as on dry land; his feeding them with manna in the wilderness, protecting them from their enemies, bringing them into the land of Canaan, and settling them there; see Psalm 78:11.

ways--of providence, &c., as usual (Psalm 25:4; Psalm 67:2).
acts--literally, "wonders" (Psalm 7:11; Psalm 78:17).
