Genesis 20:7

He is a prophet A person favoured with peculiar intercourse with God, who is made acquainted with his will and purposes in an extraordinary way, and is the interpreter of that will, and the revealer of those purposes to others. This seems to be the meaning of the appellation prophet, first, as we here see, given to Abraham in the Scriptures.

Genesis 20:9. Thou hast done deeds that ought not to be done Equivocation and dissimulation, however they may be palliated, are very ill things, and by no means to be admitted in any case. He takes it as a very great injury to himself and his family, that Abraham had thus exposed them to temptation and sin. What have I offended thee? If I had been thy worst enemy thou couldest not have done me a worse turn, nor taken a more effectual course to be revenged on me. He challenges him to assign any just cause he had to suspect them as a dangerous people for an honest man to live among. What sawest thou that thou hast done this thing? What reason hadst thou to think, that if we had known her to be thy wife, thou wouldest have been exposed to any danger by it?
