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 sin, What have I offended thee? — If I had been thy worst enemy, thou couldst not have done me a worse turn, nor taken a more effectual course to be avenged on me. Note, We ought to reckon, that those do us the greatest dislikedness in the world, that any way tempt us or expose us to sin, though they may pretend friendship, and offer that which is grateful enough to the corrupt nature. He challenges him to assign any just cause he had to suspect them as a dangerous people for an honest man to live among.
