'Once' in the Bible

I once was young and now I am old, but I have not seen a righteous person forsaken or his descendants begging for bread.

I once observed a wicked and oppressive person, flourishing like a green tree in native soil.

They say, "Wickedness is entrenched in him. Once he is brought low, he will not rise again."

Why are you in despair, my soul? Why are you disturbed within me? Hope in God, for once again I will praise him, since his presence saves me.

Why are you in despair, my soul? Why are you disturbed within me? Hope in God, for once again I will praise him, since his presence saves me and he is my God.

Why are you in despair, my soul? Why are you disturbed within me? Hope in God, because I will praise him once again, since his presence saves me and he is my God. To the Director: An instruction of the Sons of Korah.

God spoke once, but I heard it twice, "Power belongs to God."

You will increase my honor and comfort me once again.

I have sworn by my holiness once for all: I will not lie to David.
