Deuteronomy 6:7

4 Hear, Israel: Yahweh is our God; Yahweh is one:

5 and you shall love Yahweh your God with all your heart, and with all your soul, and with all your might.

6 These words, which I command you this day, shall be on your heart;

7 and you shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise up.

8 You shall bind them for a sign on your hand, and they shall be for symbols between your eyes.

9 You shall write them on the door-posts of your house, and on your gates.

10 It shall be, when Yahweh your God shall bring you into the land which he swore to your fathers, to Abraham, to Isaac, and to Jacob, to give you, great and goodly cities, which you didn`t build,
