Genesis 31:44-53   44. Now therefore come thou, let us make a covenant, I and thou; and let it be for a witness between me and thee. 45. And Jacob took a stone, and set it up for a pillar. 46. And Jacob said unto his brethren, Gather stones; and they took stones, and made an heap: and they did eat there upon the heap. 47. And Laban called it Jegar-sahadutha: but Jacob called it Galeed. 48. And Laban said, This heap is a witness between me and thee this day. Therefore was the name of it called Galeed; 49. And Mizpah; for he said, The LORD watch between me and thee, when we are absent one from another. 50. If thou shalt afflict my daughters, or if thou shalt take other wives beside my daughters, no man is with us; see, God is witness betwixt me and thee. 51. And Laban said to Jacob, Behold this heap, and behold this pillar, which I have cast betwixt me and thee; 52. This heap be witness, and this pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap and this pillar unto me, for harm. 53. The God of Abraham, and the God of Nahor, the God of their father, judge betwixt us. And Jacob sware by the fear of his father Isaac.

1 Samuel 20:14-17   14. And thou shalt not only while yet I live shew me the kindness of the LORD, that I die not: 15. But also thou shalt not cut off thy kindness from my house for ever: no, not when the LORD hath cut off the enemies of David every one from the face of the earth. 16. So Jonathan made a covenant with the house of David, saying, Let the LORD even require it at the hand of David's enemies. 17. And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul.
