15 and thou hast remembered that a servant thou hast been in the land of Egypt, and Jehovah thy God is bringing thee out thence by a strong hand, and by a stretched-out arm; therefore hath Jehovah thy God commanded thee to keep the day of the sabbath.
Matthew Henry's Commentary on Deuteronomy 5:15
Commentary on Deuteronomy 5:6-22
(Read Deuteronomy 5:6-22)
There is some variation here from Luke 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!
