ASV_Strongs(i)
  1 H3615 And it came to pass, when he had made an end H1696 of speaking H7586 unto Saul, H5315 that the soul H3083 of Jonathan H7194 was knit H5315 with the soul H1732 of David, H3083 and Jonathan H157 loved H5315 him as his own soul.
  2 H7586 And Saul H3947 took H3117 him that day, H5414 and would let H7725 him go no more home H1 to his father's H1004 house.
  3 H3083 Then Jonathan H1732 and David H3772 made H1285 a covenant, H160 because he loved H5315 him as his own soul.
  4 H3083 And Jonathan H6584 stripped H4598 himself of the robe H5414 that was upon him, and gave H1732 it to David, H4055 and his apparel, H2719 even to his sword, H7198 and to his bow, H2289 and to his girdle.
