'Instruction' in the Bible

Then the Lord said to Moses, “Behold, I will rain bread from heaven for you; and the people shall go out and gather a day’s portion every day, that I may test them, whether or not they will walk in My instruction.

Now the Lord said to Moses, “Come up to Me on the mountain and remain there, and I will give you the stone tablets with the law and the commandment which I have written for their instruction.”
