'Believed' in the Bible

I had fainted, unless I had believed to see the goodness of the LORD in the land of the living.

Because they believed not in God, and trusted not in his salvation:

For all this they sinned still, and believed not for his wondrous works.

Then believed they his words; they sang his praise.

Yea, they despised the pleasant land, they believed not his word:

I believed, therefore have I spoken: I was greatly afflicted:

Teach me good judgment and knowledge: for I have believed thy commandments.
