'Reason' in the Bible

They replied, “If you send the ark of Israel’s God away, you must not send it without an offering. You must send back a restitution offering to Him, and you will be healed. Then the reason His hand hasn’t been removed from you will be revealed.”

He took his life in his hands when he struck down the Philistine, and the Lord brought about a great victory for all Israel. You saw it and rejoiced, so why would you sin against innocent blood by killing David for no reason?”
