Genesis 18:7; Genesis 29:17; Genesis 33:13 (King James Version)

7 And Abraham ran unto the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it. 17 Leah was tender eyed; but Rachel was beautiful and well favoured. 13 And he said unto him, My lord knoweth that the children are tender, and the flocks and herds with young are with me: and if men should overdrive them one day, all the flock will die .
