Deuteronomy 5:15 Meaning and Commentary

Deuteronomy 5:15

And remember that thou wast a servant in the land of Egypt,
&c.] Even a bondservant; for Egypt was an house of bondage, and there the Israelites were made to serve in hard bondage; of which they are reminded, that their hearts might be touched with it, and inclined to show pity to persons in somewhat similar circumstances; calling to mind how sweet a little rest would have been unto them when in Egypt:

and that the Lord thy God brought thee out thence, through a mighty
hand and by a stretched out arm;
signifying that their deliverance from their state of bondage was not owing to themselves, nor to any creature, but to the mercy and kindness of God, and to his almighty power; and therefore they were under the greatest obligations to observe any command and institution of his he should think fit to make; and particularly this of the sabbath, which was made on that account, as follows:

wherefore the Lord thy God commandeth thee to keep the sabbath day;
in commemoration of their rest from Egyptian bondage.

Deuteronomy 5:15 In-Context

13 Six days shalt thou labor, and do all thy work;

14 but the seventh day is a sabbath unto Jehovah thy God: [in it] thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy man-servant, nor thy maid-servant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy man-servant and thy maid-servant may rest as well as thou.

15 And thou shalt remember that thou wast a servant in the land of Egypt, and Jehovah thy God brought thee out thence by a mighty hand and by an outstretched arm: therefore Jehovah thy God commanded thee to keep the sabbath day.

16 Honor thy father and thy mother, as Jehovah thy God commanded thee; that thy days may be long, and that it may go well with thee, in the land which Jehovah thy God giveth thee.

17 Thou shalt not kill.
