'For Us' in the Bible

The young men who grew up with him spoke to him, saying, “Thus you shall say to the people who spoke to you, saying, ‘Your father made our yoke heavy, but you make it lighter for us.’ Thus you shall say to them, ‘My little finger is thicker than my father’s loins!

But as for us, the Lord is our God, and we have not forsaken Him; and the sons of Aaron are ministering to the Lord as priests, and the Levites attend to their work.
