'Prayed' in the Bible

King Hezekiah and the prophet Isaiah son of Amoz prayed about this and cried out to heaven,

In those days Hezekiah became sick to the point of death, so he prayed to the Lord, and He spoke to him and gave him a miraculous sign.

He prayed to Him, so He heard his petition and granted his request, and brought him back to Jerusalem, to his kingdom. So Manasseh came to know that Yahweh is God.
