'Prepared' in the Bible

Then the seven angels who had the seven trumpets prepared themselves to sound them [initiating the judgments].

Then the woman fled into the wilderness where she had a place prepared by God, so that she would be nourished there for a thousand two hundred and sixty days (forty-two months; three and one-half years).

Let us rejoice and shout for joy! Let us give Him glory and honor, for the marriage of the Lamb has come [at last] and His bride (the redeemed) has prepared herself.”
