'Observes' in the Bible

For His eyes watch over a man’s ways,and He observes all his steps.

The Lord looks down from heaven;He observes everyone.

For the king of Babylon stands at the split in the road, at the fork of the two roads, to practice divination: he shakes the arrows, consults the idols, and observes the liver.

Whoever observes the day, observes it for the honor of the Lord. Whoever eats, eats for the Lord, since he gives thanks to God; and whoever does not eat, it is for the Lord that he does not eat it, yet he thanks God.
