'Call on the Name of the Lord' in the Bible

And call you on the name of your gods, and I will call on the name of the LORD: and the God that answers by fire, let him be God. And all the people answered and said, It is well spoken.

But Naaman was angry, and went away, and said, Behold, I thought, He will surely come out to me, and stand, and call on the name of the LORD his God, and strike his hand over the place, and cure the leprosy.

And it shall come to pass, that whosoever shall call on the name of the LORD shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the LORD has said, and in the remnant whom the LORD shall call.

And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
