1 Samuel 16:7 reveals God looks at the heart — the basis for David's claim that God knows him intimately.

Psalm 139:1 expresses David's same confidence that God has searched and known him — a direct thematic parallel from the same author.

1 Chronicles 17:18 is the parallel account, nearly identical: 'What more can David say... for you know your servant.'

Genesis 18:19 shows God choosing Abraham to teach his household righteousness — paralleling God's intimate knowledge of David as His chosen servant.

John 2:25 asserts Jesus knows what is in man — extending the theme of divine knowledge of individuals to Christ's omniscience.
