Deuteronomy 5:21 MEANING

Deuteronomy 5:21
(21) His field.--These words are not found in Exodus 20. The children of Israel had now become, or were just about to become, landowners; hence the addition is appropriate in this place. There is also another slight verbal alteration. One word only is used for "covet" in Exodus 20:17; here two are employed. The idea of the one is to "delight in," and the other to "lust after."

5:6-22 There is some variation here from Ex 20 as between the Lord's prayer in Mt 6 and Lu 11. It is more necessary that we tie ourselves to the things, than to the words unalterably. The original reason for hallowing the sabbath, taken from God's resting from the work of creation on the seventh day, is not here mentioned. Though this ever remains in force, it is not the only reason. Here it is taken from Israel's deliverance out of Egypt; for that was typical of our redemption by Jesus Christ, in remembrance of which the Christian sabbath was to be observed. In the resurrection of Christ we were brought into the glorious liberty of the children of God, with a mighty hand, and an outstretched arm. How sweet is it to a soul truly distressed under the terrors of a broken law, to hear the mild and soul-reviving language of the gospel!Neither shalt thou desire thy neighbour's wife,.... Here a neighbour's wife is put before his house, different from Exodus 20:17 and "his field" is added, which with what follows take in everything that is a man's property; and which is not to be desired or coveted in an unlawful manner by another, and much less should any means be made use of to deprive him of it; but "lust" is the thing intended and prohibited, be it after what it may, which is another man's: see Matthew 5:28, of a man's field, see Isaiah 5:8.
