Question 1

What does Isaiah 42:15 mean?

Accepted Answer

Isaiah 42:15 describes God’s power to completely transform the natural world, saying He will lay waste to mountains and hills, dry up all their plants, turn rivers into islands, and dry up pools. This verse uses dramatic language to show that nothing in creation can stand in the way of God’s purpose. In this part of Isaiah, God is speaking through the prophet to people who are discouraged and in exile. The verse comes in a section where God is introducing His chosen servant and promising to bring justice and new hope. By describing such sweeping changes in nature, Isaiah is emphasizing that God’s authority is absolute—He can overturn even the most permanent and unchangeable things to fulfill His promises.

Question 2

The Hebrew behind Isaiah 42:15

Accepted Answer

The word “waste” (חָרַב, ḥārav) means to lay waste or devastate. It stresses the total destruction or emptiness God can bring, not just a minor change. “Mountains” (הָרִים, harim) and “hills” (גְּבָעוֹת, geva‘ot) refer to the most solid and enduring parts of the landscape, highlighting that even the strongest things are under God’s control. “Rivers” (נָהָר, nahar) and “pools” (אֲגַם, agam) are sources of life and fertility in the land. Drying them up shows God’s ability to remove what people depend on, if He chooses. The word “islands” (אִי, ’i) can also mean dry land or coastlands. Here, it suggests that God can so thoroughly change a river that it becomes dry land, something entirely new.
