Deuteronomy 14:23

Deuteronomy 4:10
Specially the day that thou stoodest before the LORD thy God in Horeb, when the LORD said to me, Assemble the people to me, and I will make them hear my words, that they may learn to fear me all the days that they shall live upon the earth, and that they may teach their children.
Deuteronomy 12:5-7
But the place which the LORD your God shall choose out of all your tribes to put his name there, even his habitation shall ye seek, and thither thou shalt come:
Deuteronomy 12:17-18
Thou mayest not eat within thy gates the tithe of thy corn, or of thy wine, or of thy oil, or the firstlings of thy herds or of thy flock, nor any of thy vows which thou vowest, nor thy free-will-offerings, or heave-offering of thy hand:
Deuteronomy 15:19-20
All the firstling males that come of thy herd and of thy flock thou shalt sanctify to the LORD thy God: thou shalt do no work with the firstling of thy bullock, nor shear the firstling of thy sheep.
