'Comprehension' in the Bible

I am Your servant; give me understanding [the ability to learn and a teachable heart]That I may know Your testimonies.

The unfolding of Your [glorious] words give light;Their unfolding gives understanding to the simple (childlike).

Your righteous testimonies are everlasting;Give me understanding [the ability to learn and a teachable heart] that I may live.

Tav.Let my [mournful] cry come before You, O Lord;Give me understanding [the ability to learn and a teachable heart] according to Your word [of promise].
