That's not what it means either in that context.
“Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations.”
(Jeremiah 1:5)
What does it mean that God knew Jeremiah before even one of his cells were formed?
The Hebrew word for know is
yada (יָדַע).
As in English, yada has a wide range of meanings from knowing someone intimately to knowing about them; from knowing how to do something to perceiving, learning, and experiencing something.
Yada appears 947 times in the Hebrew Scriptures, but we’ll focus here on what God knows about us and what it could mean that He even knew us before He knit us in our womb.
In Scripture, we see that God has intimate knowledge of us at the depth of our character and soul:
- He knows the hearts of all men (1 Kings 8:39; 2 Chronicles 6:30), those who are His servants (2 Samuel 7:20; Nahum 1:7; 1 Chronicles 17:18) and those who are false, vain, and deceitful (Job 11:11).
- He keeps the lowly close to His thoughts, but only knows the haughty from afar (Psalm 138:6).
- He knows our words before they are spoken (Psalm 139:4) and the distresses of our lives (Psalm 31:7).
And He knows you, “Even the hairs of your head are all numbered.”
(Matthew 10:30)
And in the context it also means " chosen."
