Ver. 18-20. Therefore shall ye lay up these my words in your heart, and in your soul Treasure up the laws of God delivered to them in their minds, retain them in their memories, and cherish a cordial affection for them; which would be an antidote against apostasy, idolatry, and other sins, ( Psalms 119:11 )
and bind them for a sign upon your hand, that they may be as frontlets between your eyes; of this and the two following verses, (See Gill on Deuteronomy 6:7), (See Gill on Deuteronomy 6:8), (See Gill on Deuteronomy 6:9).
16
Be careful, or you will be fooled and will turn away to serve and worship other gods.
17
If you do, the Lord will become angry with you and will shut the heavens so it will not rain. Then the land will not grow crops, and you will soon die in the good land the Lord is giving you.
18
Remember my words with your whole being. Write them down and tie them to your hands as a sign; tie them on your foreheads to remind you.
19
Teach them well to your children, talking about them when you sit at home and walk along the road, when you lie down and when you get up.
