Answer: Numbers 1 and 5, David.
Numbers 2 and 4, Moses.
Numbers 3 and 6, Joseph.
Explanation: David became popular after killing the giant Goliath and jealous King Saul attempted to kill him a few times unsuccessfully. David had to flee into the wilderness for safety but after Saul died in battle, David was exalted to the position of the next King of Israel.
Moses' attempt at liberating his people from slavery (including killing an Egyptian) further incurred Pharaoh's wrath and Moses had to flee when his own people condemned his action in their defence. He was eventually called while in exile to return to Egypt for the purpose of leading his people out of slavery and hence became their leader for the next few years.
Joseph was rejected and despised by his jealous brothers and they sold him off into slavery. It was while he was in prison as a slave that he was divinely blessed with the wisdom to interprete dreams and as a reward for interpreting Pharoah's dream, he was appointed as a ruler second in command to Pharaoh.
