'Empty handed' in the Bible

I will grant this people public favor with the Egyptians, and as a result, when you leave you won't go empty-handed.

You shall observe the Feast of Unleavened Bread; for seven days you are to eat unleavened bread, as I commanded you, at the appointed time in the month Abib, for in it you came out of Egypt. And none shall appear before Me empty-handed.

You are to redeem the firstborn of a donkey with a sheep, and if you don't redeem it, you are to break its neck. You are to redeem every firstborn of your sons, and no one is to appear before me empty-handed.
