'Upon' in the Bible

The Spirit of the LORD will come upon you, and you'll prophesy with them and be changed into a different person.

When they arrived there at Gibeah, a band of prophets was right there to meet them. The Spirit of God came upon Saul, and he prophesied along with them.

Is it not the wheat harvest today? I'll call upon the LORD, and he will send thunder and rain. Then you will know and understand that you have done a great evil in the sight of the LORD by asking for a king for yourselves."

Samuel called upon the LORD that same day, and the LORD sent thunder and rain. So all the people greatly feared the LORD and Samuel.
