For that very moment of the abomination of desolation, the very beginning of great tribulation,

when they are to flee into the mountains, doesn't Jesus tell them to pray that it not be in the winter or on a sabbath day?

 

Matthew 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)

  16 Then let them which be in Judaea flee into the mountains:

  20 But pray ye that your flight be not in the winter, neither on the sabbath day:

  21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.

 

Doesn't it appear that Jesus expects them to not only flee, but also to pray for what he said?

Why pray that, if it is supposed to happen on a fixed day in a fixed time of the year?

If he tells them to pray that, does he expect to answer those prayers?

Apparently, if they pray that, then it won't happen in the winter nor on the sabbath day?

But if they don't pray that, is it possible that it could happen in the winter, and/or on the sabbath day?
