The answer is: The mountains

Mark 13:14

In Mark 13, Jesus unpacks what’s vividly known as the Olivet Discourse, offering his disciples dire warnings about the tumultuous trials that lie ahead. When He mentions the "abomination of desolation," He is hinting at something many Jewish listeners would recognize from the book of Daniel, a perplexing yet powerful symbol of desecration. This referring might have roused images of Antiochus Epiphanes desecrating the Temple back in 167 BC!

Now, when it comes to the instruction to "flee to the mountains," think about the geographical context. Judea is dotted with rugged hills and rocky terrains—ideal for hasty escape. The mountains also evoke a deeper narrative in the Bible, often portrayed as refuges or places of divine encounter. Just like when Moses received the Law atop Mount Sinai, or later, when Jesus retreated to the mountains to pray, these high places symbolize a connection with the divine offering safety and solace.

Interestingly, the reference to fleeing can remind us of real-life events too. History records that many faithful in Judea indeed took heed of this wisdom during the Roman siege of Jerusalem in 70 A.D., making it to the hills and saving themselves amidst destruction. This passage not only anticipates future tribulations but underscores a timeless principle of preparation and divine provision for souls committed to seeking refuge. Pretty inspiring, right? It's a reminder that sometimes, facing daunting scenarios, a little wisdom and quick thinking can save the day!
