'Value' in the Bible

Then he sent a third captain of fifty with his fifty men; and the third captain of fifty went up, and falling on his knees before Elijah, requesting mercy of him, said, O man of God, let my life and the life of these your fifty servants be of value to you.

For fire came down from heaven and put an end to the first two captains of fifty and their fifties; but now let my life be of value in your eyes.

And they went against his rules, and the agreement which he made with their fathers, and his laws which he gave them; they gave themselves up to things without sense or value, and became foolish like the nations round them, of whom the Lord had said, Do not as they do.
