'Please' in the Bible

David responded to God, "I sinned greatly by behaving this way. But now I am asking you, please remove the guilt of your servant, since I have acted very foolishly."

So David replied to Gad, "This is a very bad choice for me to make! Let me now please fall into the hand of the LORD, because his mercy is very great, but may I never fall into human hands!"

David told God, "Wasn't I the one who ordered the census of the population? Wasn't it I who sinned and acted wickedly? Now as for these sheep, what have they done? LORD God, please let your hand be against me and my ancestral household, but don't let your people be ravaged by plague!"

Then David told the entire assembly, "Bless the LORD your God, please." So the entire assembly blessed the LORD God of their ancestors, bowing their heads and falling in the LORD's presence and before the king.
