Genesis

²⁴And Abraham said, I will swear. ²⁵And Abraham reproved Abimelech because of the well of water, which Abimelech's servants had violently taken away. ²⁶And Abimelech said, I know not who hath done this thing: neither didst thou tell me, neither yet heard I of it, but today. ²⁷And Abraham took sheep and oxen, and gave them unto Abimelech; and they two made a covenant. ²⁸And Abraham set seven ewe lambs of the flock by themselves. ²⁹And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves? ³⁰And he said, These seven ewe lambs shalt thou take of my hand, that it may be a witness unto me, that I have digged this well.
