'Descendants' in the Bible

Then they brought the head of Ish-bosheth to David at Hebron and said to the king, “Behold, the head of Ish-bosheth the son of Saul, your enemy, who sought your life; thus the Lord has given my lord the king vengeance this day on Saul and his descendants.”

Then Ishbi-benob, who was among the descendants of the giant, the weight of whose spear was three hundred shekels of bronze in weight, was girded with a new sword, and he intended to kill David.

Now it came about after this that there was war again with the Philistines at Gob; then Sibbecai the Hushathite struck down Saph, who was among the descendants of the giant.

“He is a tower of deliverance to His king,And shows lovingkindness to His anointed,To David and his descendants forever.”
