'Instruction' in the Bible

So it shall be a reproach and a taunt, an instruction and an astonishment, to the nations that are around you, when I shall execute judgments on you in anger and in wrath, and in wrathful rebukes; (I, Yahweh, have spoken it;)

they shall enter into my sanctuary, and they shall come near to my table, to minister to me, and they shall keep my instruction.

[It shall be] for the priests who are sanctified of the sons of Zadok, who have kept my instruction, who didn't go astray when the children of Israel went astray, as the Levites went astray.
