Genesis 20:7
“Now therefore restore the man his wife; for he is a prophet, and he shall pray for thee, and thou shalt live: and if thou restore her not, know thou that thou shalt surely die, thou, and all that are thine.”
KJV
Read in Genesis 20Meaning
Abimelech is told to return Sarah, and Abraham is identified as a prophet whose prayer will accompany the restoration.
Read carefully
Prophetic status does not make Abraham's deceptive conduct good; biblical vocation and human failure can appear in the same person.
Reflection
Restoration requires concrete action, not only recognition that something has gone wrong.
