King David's son Absalom tried to take the throne from his father. David sent an army to oppose him and won. As Absalom was fleeing on a mule his hair, which was recorded as weighing 200 shekels (2Samuel 14:26), got him stuck in a tree he was riding under. After Joab, one of David's military captains, found out that Absalom was stuck in a tree he had him killed (2Samuel 14).
Jacob, Esau and the number 200
Most people are aware that Jacob tricked his twin brother Esau out of his birthright (using a bowl of red soup, Genesis 25:29 - 34) and blessing (by pretending to be him when their virtually blind father Isaac gave the family blessing, Genesis 27). Esau's vow to kill his brother (Genesis 27:41) is enough for Jacob to flee Canaan. Years later, God commands Jacob to go back home. The idea of running into his brother while traveling, however, scares Jacob. Messengers sent to his brother return to Jacob with the news that Esau is coming to meet him with 400 men! Afraid of his brother exacting revenge on him and his family, Jacob sends him a large gift that includes 200 she-goats and 200 ewes (Genesis 32:14). Ultimately, through God's grace, the twin brothers meet peaceably and Jacob is able to return home safely.
Additional information on the Biblical Meaning of 200
King Saul, when his hatred for David began to grow because he saw God was with him, devised a way for someone other than himself to kill the future king. Saul's plan was to use the Philistines, Israel's sworn enemy, as the means by which David could lose his life. The king offers David the hand of his daughter Michal (who loved David) in marriage IF he brought back the foreskins from 100 slain Philistines. David not only accepts the challenge, he and his men kill DOUBLE the number of Philistines required for Michal's hand. David returns to Saul with a bag of 200 Philistine foreskins and marries Michal (1Samuel 18).
