'Observes' in the Bible

and follows my statutes and observes my regulations by carrying them out. That man is righteous; he will certainly live, declares the sovereign Lord.

"Yet you say, 'Why should the son not suffer for his father's iniquity?' When the son does what is just and right, and observes all my statutes and carries them out, he will surely live.

"But if the wicked person turns from all the sin he has committed and observes all my statutes and does what is just and right, he will surely live; he will not die.
