Deuteronomy 6:7 tells Israel to teach God's commands diligently to whom?

Answer: Their children

Israel was to teach God's words diligently to their children, speaking of them at home, on the road, lying down and getting up.

“These words I am commanding you today are to be upon your hearts. And you shall teach them diligently to your children and speak of them when you sit at home and when you walk along the road, when you lie down and when you get up.”— Deuteronomy 6:6-7 (BSB)
