TSK · Genesis 47:22

Pharaoh called Joseph's name Zaphenath-Paneah; and he gave him Asenath, the daughter of Potiphera priest of On as a wife. Joseph went out over the land of Egypt.

Joseph made it a statute concerning the land of Egypt to this day, that Pharaoh should have the fifth. Only the land of the priests alone didn't become Pharaoh's.

Then the heads of fathers' houses of the Levites came near to Eleazar the priest, and to Joshua the son of Nun, and to the heads of fathers' houses of the tribes of the children of Israel.

Also we inform you, that touching any of the priests and Levites, the singers, porters, Nethinim, or servants of this house of God, it shall not be lawful to impose tribute, custom, or toll, on them.

Take no bag for your journey, neither two coats, nor shoes, nor staff: for the laborer is worthy of his food.

But let him who is taught in the word share all good things with him who teaches.

Let the elders who rule well be counted worthy of double honor, especially those who labor in the word and in teaching.
