'Once' in the Bible

So Yahweh left those nations; he did not drive them out at once, and he did not give them into the hand of Joshua.

And Gideon said to God, "{Do not let your anger burn} against me; let me speak once more. Please let me test once more with the fleece; let the fleece be dry, and let there be dew on the ground."

Once again Jephthah sent messengers to the king of the {Ammonites},

and Phinehas son of Eleazar, son of Aaron, [was] standing {before it} [to minister] in those days), saying, "Should we go out once more to battle against the descendants of Benjamin our relatives, or should we stop?" And Yahweh said, "Go up tomorrow; I will give them into your hand."
