Charles Spurgeon Commentary Luke 21:19-24

"In your patience ye shall win your souls. But when ye see Jerusalem compassed with armies, then know that her desolation is at hand. Then let them that are in Judaea flee unto the mountains; and let them that are in the midst of her depart out; and let not them that are in the country enter therein. For these are days of vengeance, that all things which are written may be fulfilled. Woe unto them that are with child and to them that give suck in those days! for there shall be great distress upon the land, and wrath unto this people. And they shall fall by the edge of the sword, and shall be led captive into all the nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled." — Luke 21:19-24 (ASV)

And it is so even to this day. Here is another instance in which the Lord instructed his people to expect his coming, and yet at the same time told them that he would not come as long as Jerusalem should be trodden down by the Gentiles. Until the times of the Gentiles be fulfilled means the time when the Messiah will gather in those Gentiles to himself; for, when he will appear, they will look on him whom they have despised, and turn to him whom they have so long rejected.
