'Please' in the Bible

David said to God, “I have sinned greatly, in that I have done this thing. But now, please take away the iniquity of Your servant, for I have done very foolishly.”

David said to Gad, “I am in great distress; please let me fall into the hand of the Lord, for His mercies are very great. But do not let me fall into the hand of man.”

David said to God, “Is it not I who commanded to count the people? Indeed, I am the one who has sinned and done very wickedly, but these sheep, what have they done? O Lord my God, please let Your hand be against me and my father’s household, but not against Your people that they should be plagued.”
