'Empty handed' in the Bible

And when you send him [out] free from you, you shall not send him [away] empty-handed.

Three times in the year all [of] your males shall appear {before } Yahweh your God at the place that he will choose, at the Feast of Unleavened Bread and at the Feast of Weeks and at the Feast of Booths, and they shall not appear {before Yahweh} empty-handed.
