I have removed his shoulder from the burden. Here God begins to recount the benefits which he had bestowed upon the Israelites, and the many ways in which he had laid them under obligations to him. The more galling the bondage was from which they had been delivered, the more desirable and precious was their liberty. When, therefore, it is affirmed that their burdens were so heavy that they stooped under them, and that they were doomed to the labor of making bricks, and to other slavish and toilsome occupations, the comparison of this their first state with their condition afterwards is introduced to illustrate the more strikingly the greatness of the blessing of their deliverance. Let us now apply this to ourselves, and elevate our minds to a higher subject, of which it was an image. As God has not only withdrawn our shoulders from a burden of brick, and not only removed our hands from the kilns, but has also redeemed us from the cruel and miserable tyranny of Satan, and drawn us from the depths of hell, the obligations under which we lie to him are of a much more strict and sacred kind than those under which he had brought his ancient people.

I removed his shoulder from the burden - The burden which the people of Israel were called to hear in Egypt. The reference is undoubtedly to their burdens in making bricks, and conveying them to the place where they were to be used; and perhaps also to the fact that they were required to carry stone in building houses and towns for the Egyptians. Compare Exodus 1:11-14; Exodus 5:4-17. The meaning is, that he had saved them from these burdens, to wit, by delivering them from their hard bondage. The speaker here evidently is God. In the previous verse it is the people. Such a change of person is not uncommon in the Scriptures.
His hands were delivered from the pots - Margin, as in Hebrew, passed away. That is, they were separated from them, or made free. The word rendered pots usually has that signification. Job 41:20; 1-Samuel 2:14; 2-Chronicles 35:13; but it may also mean a basket. Jeremiah 24:2; 2-Kings 10:7. The latter is probably the meaning here. The allusion is to baskets which might have been used in carrying clay, or conveying the bricks after they were made: perhaps a kind of hamper that was swung over the shoulders, with clay or bricks in each - somewhat like the instrument used now by the Chinese in carrying tea - or like the neck-yoke which is employed in carrying sap where maple sugar is manufactured, or milk on dairy farms. There are many representations on Egyptian sculptures which would illustrate this. The idea is that of a burden, or task, and the allusion is to the deliverance that was accomplished by removing them to another land.

I removed his shoulder from the burden: his hands were delivered from the (f) pots.
(f) If they were never able to give sufficient thanks to God, for this deliverance from corporal bondage, how much more are we indebted to him for our spiritual deliverance from the tyranny of Satan and sin?

I removed his shoulder from the burden,.... These are the words of God, declaring how he had delivered the Israelites from the oppression and cruelty of the Egyptians; who made their lives bitter in hard bondage, and obliged them to carry heavy loads of bricks upon their shoulders:
his hands were delivered from the pots, or "baskets" (c); into which the bricks were put when made, and carried on their shoulders; or from making of pots, as Kimchi, who thinks the Israelites were employed in making pots of clay as well as bricks; see Psalm 68:13, the Targum is,
"his hands withdrew themselves from casting clay into the pots:''
the whole is typical of the saints' deliverance by Christ from the bondage of sin, Satan, and the law.
(c) "a sporta, a cophino", Gejerus, Amama, Michaelis.

God's language alludes to the burdensome slavery of the Israelites.

It is a gentle but profoundly earnest festival discourse which God the Redeemer addresses to His redeemed people. It begins, as one would expect in a Passover speech, with a reference to the סבלות of Egypt (Exodus 1:11-14; Exodus 5:4; Exodus 6:6.), and to the duwd, the task-basket for the transport of the clay and of the bricks (Exodus 1:14; Exodus 5:7.).
(Note: In the Papyrus Leydensis i. 346 the Israelites are called the "Aperiu (עברים), who dragged along the stones for the great watch-tower of the city of Rameses," and in the Pap. Leyd. i. 349, according to Lauth, the "Aperiu, who dragged along the stones for the storehouse of the city of Rameses.")
Out of such distress did He free the poor people who cried for deliverance (Exodus 2:23-25); He answered them בּסתר רעם, i.e., not (according to Psalm 22:22; Isaiah 32:2): affording them protection against the storm, but (according to Psalm 18:12; Psalm 77:17.): out of the thunder-clouds in which He at the same time revealed and veiled Himself, casting down the enemies of Israel with His lightnings, which is intended to refer pre-eminently to the passage through the Red Sea (vid., Psalm 77:19); and He proved them (אבחנך, with ŏ contracted from ō, cf. on Job 35:6) at the waters of Merbah, viz., whether they would trust Him further on after such glorious tokens of His power and loving-kindness. The name "Waters of Merı̂bah," which properly is borne only by Merı̂bath Kadesh, the place of the giving of water in the fortieth year (Numbers 20:13; Numbers 27:14; Deuteronomy 32:51; Deuteronomy 33:8), is here transferred to the place of the giving of water in the first year, which was named Massah u-Merı̂bah (Exodus 17:7), as the remembrances of these two miracles, which took place under similar circumstances, in general blend together (vid., on Psalm 95:8.). It is not now said that Israel did not act in response to the expectation of God, who had son wondrously verified Himself; the music, as Seal imports, here rises, and makes a long and forcible pause in what is being said. What now follows further, are, as the further progress of Psalm 81:12 shows, the words of God addressed to the Israel of the desert, which at the same time with its faithfulness are brought to the remembrance of the Israel of the present. העיד בּ, as in Psalm 50:7; Deuteronomy 8:19, to bear testimony that concerns him against any one. אם (according to the sense, o si, as in Psalm 95:7, which is in many ways akin to this Psalm) properly opens a searching question which wishes that the thing asked may come about (whether thou wilt indeed give me a willing hearing?!). In Psalm 81:10 the key-note of the revelation of the Law from Sinai is struck: the fundamental command which opens the decalogue demanded fidelity to Jahve and forbade idol-worship as the sin of sins. אל זר is an idol in opposition to the God of Israel as the true God; and אל נכר, a strange god in opposition to the true God as the God of Israel. To this one God Israel ought to yield itself all the more undividedly and heartily as it was more manifestly indebted entirely to Him, who in His condescension had chosen it, and in His wonder-working might had redeemed it (המּעלך, part. Hiph. with the eh elided, like הפּדך, Deuteronomy 13:6, and אכלך, from כּלּה, Exodus 33:3); and how easy this submission ought to have been to it, since He desired nothing in return for the rich abundance of His good gifts, which satisfy and quicken body and soul, but only a wide-opened mouth, i.e., a believing longing, hungering for mercy and eager for salvation (Psalm 119:131)!

Pots - This word denotes all those vessels wherein they carried water, straw, lime, or bricks.
