Neither shalt thou steal.

Wesley's Notes

5:19 Neither shalt thou steal - Have you seriously considered, that these houses, lands, money, or goods, which you are used to call your own, are not your own, but belong to another, even God? Have you ever considered, that God is the sole proprietor of heaven and earth? The true owner of every thing therein? Have you considered, that he has only lent them to you? That you are but a steward of your Lord's goods? And that he has told you expressly the uses and purposes for which he intrusts you with them? Namely, for the furnishing first yourselves, and then as many others as you can, with the things needful for life and godliness? Have you considered, that you have no right at all, to apply any part of them to any other purpose? And that if you do, you are as much a robber of God, as any can be a robber of you?

Matthew Henry's Concise Commentary

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!
