'Observes' in the Bible

“But if the wicked man turns from all his sins which he has committed and observes all My statutes and practices justice and righteousness, he shall surely live; he shall not die.

I gave them My statutes and informed them of My ordinances, by which, if a man observes them, he will live.

But the house of Israel rebelled against Me in the wilderness. They did not walk in My statutes and they rejected My ordinances, by which, if a man observes them, he will live; and My sabbaths they greatly profaned. Then I resolved to pour out My wrath on them in the wilderness, to annihilate them.

But the children rebelled against Me; they did not walk in My statutes, nor were they careful to observe My ordinances, by which, if a man observes them, he will live; they profaned My sabbaths. So I resolved to pour out My wrath on them, to accomplish My anger against them in the wilderness.
