The book of 1st and 2nd Samuel (originally written as one book) gives us a glimpse of who Jesus is in the Old Testament (O.T).
2nd Samuel talks about a man named Abishai (2 Samuel 23), who is one of David’s fighting men, along with Eleazar, Shammah and Benaiah (who were valiant in battle, mighty men skilled in the art of war and fought fearlessly) of whom it is said that He was more honorable and made commander over even the chiefs of the armies of David (2 Samuel 23:19). 1 Samuel 26:6-8 records that valiant Abishai goes with David to the camp of Saul, going behind enemy lines. We named our Son’s middle name after this character and also become of its meaning. Abishai means – Gift of God.
Romans 6:23 says that the wages of sin is death, but the Gift of God (but the Abishai) is eternal life through Jesus Christ our Lord (who went behind enemy (ha shaitan – adversary) lines to pay for this gift.
In 2nd Samuel, Jesus is the Abishai (gift of God) who went behind enemy lines to be with us as we walk in the valley of the shadow of death, on earth.
