The Hebrew Word for "Heart" in Psalm 139 Means the Whole Inner Person
When David asked God to search his "heart," what was he actually asking?
"God, examine me and know my heart." — Psalm 139:23, Expanded Bible— Psalm 139:23
In Psalm 139:23, David prays: "God, examine me and know my heart." The word he uses is levav (לֵבָב) — and while English readers instinctively picture emotion, the Hebrew carries a far broader meaning.
In biblical Hebrew, levav refers to the whole inner life of a person: intellect, reason, intention, will, and moral conscience. It is the place where you think, decide, and commit — not just where you feel. When Proverbs 4:23 says "Guard your heart, for it is the wellspring of life," it is speaking of the source of your choices and values.
This usage appears throughout Scripture: Solomon was given "a wise and discerning heart" (1 Kings 3:12) — referring to his intellect and moral judgment. God promises in Jeremiah 31:33 to write His law on the lev — the inner moral center. Even Pharaoh's "hardened heart" (Exodus 7–11) refers to his stubborn will refusing to relent.
When David asked God to examine his levav, he was not asking for an emotional audit. He was inviting God into the deepest layer of his motives, decisions, and moral commitments.
Why It Matters
God's interest in the heart is not sentimental. He is examining the decision-making center, the place of intention, the seat of covenant loyalty or disloyalty. When the levav is aligned with His Word, everything else follows.
