'Once' in the Bible

“These things you have done and I kept silent;You thought that I was just like you.Now I will reprimand and denounce you and state the case in order before your eyes.

God has spoken once,Twice I have heard this:That power belongs to God.

You, even You, are to be feared [with the submissive wonder of reverence];Who may stand in Your presence when once You are angry?

Once You spoke in a vision to Your godly ones,And said, “I have given help to one who is mighty [giving him the power to be a champion for Israel];I have exalted one chosen from the people.

“Once [for all] I have sworn by My holiness, [My vow which cannot be violated];I will not lie to David.
