Rashi, on Gen 20:7

“Now therefore restore the man his wife, for he is a prophet: and he shall pray for thee, and thou shalt live: but if thou wilt not restore her, know that thou shalt surely die, thou and all that are thine.”

“השב אשת האיש RESTORE THE MAN’S WIFE and do not think that she will be repulsive in his eyes and that he will not take her back or that he will hate you and will not pray for you כי נביא הוא FOR HE IS A PROPHET and he knows that you have not touched her (Genesis Rabbah 52:8); therefore—ויתפלל בעדך HE WILL PRAY FOR THEE.”
