Psalm 66:10

Then he cried out to Yahweh, and Yahweh showed him a tree; and he threw it into the waters, and the waters became sweet. There He set for them a statute and a judgment, and there He tested them.

“But He knows the way I take; When He has tested me, I shall come forth as gold.

You have tested my heart; You have visited me by night; You have tried me and You find nothing; I have purposed that my mouth will not transgress.

Until the time that his word came to pass, The word of Yahweh refined him.

If any man’s work is burned up, he will suffer loss, but he himself will be saved, yet so as through fire.
