Yada: To Know
Yada is one of the most common verbs in the Old Testament, and one of the widest in meaning. It can describe knowing a fact, recognizing a face, or the closest human intimacy there is. Scripture uses the same word for all of it, because in Hebrew thought, real knowledge is rarely just information.
Pronounced yaw-dah'. verb.
Yada means to know, but its range runs far past facts: it covers relationship, experience, and intimacy, the difference between knowing about someone and truly knowing them.
When Genesis says Adam “knew” his wife, it uses yada for the most intimate human closeness available, not a euphemism borrowed from elsewhere but the word’s own natural range. The same verb describes God knowing Jeremiah before he was formed in the womb, and Israel being told to know that the Lord is God. Facts, relationship, and covenant loyalty all sit inside one word.
That is what makes Psalm 139 so striking. When David says “thou hast searched me, and known me,” he is not describing God’s data about him. He is describing being fully known, the way you know someone you have lived beside for years, and finding that this searching, complete knowledge is somehow good news rather than exposure to fear.
