1 Samuel 18:1-4
And it came to pass, when he had made an end of speaking unto Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul. And Saul took him that day, and would let him go no more home to his father's house. Then Jonathan and David made a covenant, because he loved him as his own soul. And Jonathan stripped himself of the robe that was upon him, and gave it to David, and his garments, even to his sword, and to his bow, and to his girdle.
1 Samuel 18:20
And Michal Saul's daughter loved David: and they told Saul, and the thing pleased him.
1 Samuel 23:16-18
And Jonathan Saul's son arose, and went to David into the wood, and strengthened his hand in God. And he said unto him, Fear not: for the hand of Saul my father shall not find thee; and thou shalt be king over Israel, and I shall be next unto thee; and that also Saul my father knoweth. And they two made a covenant before the LORD: and David abode in the wood, and Jonathan went to his house.
2 Samuel 1:17-27
And David lamented with this lamentation over Saul and over Jonathan his son: (Also he bade them teach the children of Judah the use of the bow: behold, it is written in the book of Jasher.) The beauty of Israel is slain upon thy high places: how are the mighty fallen! Tell it not in Gath, publish it not in the streets of Askelon; lest the daughters of the Philistines rejoice, lest the daughters of the uncircumcised triumph. read more
