'Sir' in the Bible

Jael went out to greet Sisera. "Turn aside, sir!" she told him. "Turn aside to me! Don't be afraid." So he turned aside to her and entered her tent, where she concealed him behind a curtain.

But Gideon replied, "Right" Sir, if the LORD is with us, then why has all of this happened to us? And where are all of his miraculous works that our ancestors recounted to us when they said, "The LORD brought us up from Egypt, didn't he?' But now the LORD has abandoned us and given us over to Midian!"

"Right"," Gideon responded. "Sir, how will I deliver Israel? Look my family is the weakest in Manasseh, and I'm the youngest in my father's household."
