Advent (from the Latin word adventus, meaning "coming") is a season of the Christian church, the period of expectant waiting and preparation for the celebration of the Nativity of Jesus, in other words, the period immediately before Christmas.
10Again the LORD spoke to Ahaz, 11"Ask a sign of the LORD your God; let it be deep as Sheol or high as heaven." 12But Ahaz said, "I will not ask, and I will not put the LORD to the test." 13And he said, "Hear then, O house of David! Is it too little for you to weary men, that you weary my God also? 14Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. 15He shall eat curds and honey when he knows how to refuse the evil and choose the good. 16For before the boy knows how to refuse the evil and choose the good, the land whose two kings you dread will be deserted. 17The LORD will bring upon you and upon your people and upon your father’s house such days as have not come since the day that Ephraim departed from Judah—the king of Assyria." —Isaiah 7:10-17 ESVIsaiah 14:9 (above) from the Latin Vulgate [emphasis added]:
infernus subter conturbatus est in occursum adventus tui suscitavit tibi gigantas omnes principes terrae surrexerunt de soliis suis omnes principes nationumThe Hebrew word from which the Latin is derrived for this verse is בוא bow' which means, "to go in, enter, come, go, come in.
