Albert Barnes Commentary Jeremiah 18:14

"Shall the snow of Lebanon fail from the rock of the field? [or] shall the cold waters that flow down from afar be dried up?" — Jeremiah 18:14 (ASV)

Rather, Will the snow of Lebanon fail from the rock of the field? The meaning probably is, “Will the snow of Lebanon fail from its rocks which tower above the land of Israel?” The appeal of the prophet is to the unchangeableness of one of nature’s most beautiful phenomena, the perpetual snow upon the upper summits of Lebanon.

Shall the cold ... - literally, shall the strange, that is, foreign, cool, down-flowing waters be plucked up? The general sense is: God is Israel’s Rock, from whom the never-failing waters flow (Jeremiah 2:13); but men may and do abandon the cool waters which descend from above to seek their happiness in channels of their own digging.
