How:
Isaiah 28:10 (NKJV)
For precept must be upon precept, precept upon precept,
Line upon line, line upon line,
Here a little, there a little.”
When:
Deut. 6:6-10 (NLT)
And you must commit yourselves wholeheartedly to these commands I am giving you today. Repeat them again and again to your children. Talk about them when you are at home and when you are away on a journey, when you are lying down and when you are getting up again. Tie them to your hands as a reminder, and wear them on your forehead. Write them on the doorposts of your house and on your gates.
Enough said 🙂
