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 labour, and do all thy work;

14 but the seventh day is the sabbath of Jehovah thy God: thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy bondman, nor thy handmaid, nor thine ox, nor thine ass, nor any of thy cattle, nor thy sojourner that is within thy gates; that thy bondman and thy handmaid may rest as well as thou.

15 And thou shalt remember that thou wast a bondman in the land of Egypt, and that Jehovah thy God brought thee out thence with a powerful hand and with a stretched-out arm; therefore Jehovah thy God hath commanded thee to observe the sabbath day.

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

17 Thou shalt not kill.
