What does Isaiah 25:10 mean?
This statement seems like a drastic change of mood. Isaiah has shown the grace of God in removing the shroud of death forever from His people. The Lord has wiped away their tears and removed the reproach of sin. It's the moment that every human heart longs for at the deepest levels (Isaiah 25:7–8). The people gathered respond with joy. They sing about their years of waiting. They believed God, so they waited for His salvation. Now that waiting is at an end. The Lord's salvation has come (Isaiah 25:9).In contrast, those opposed to God would not wait on Him to keep His promises. Many mocked the Jewish people for continuing to believe in what they could not see. The same often happens to Christians today. Israel's neighbor, Moab, stands as a representative of those who would not trust in the Lord and would not wait for Him to save. Moab was a frequent enemy of Israel (Joshua 24:9; Judges 3:12; 2 Kings 1:1).
Isaiah provides a vivid, somewhat disgusting image. The Lord rests one hand on Mount Zion and smears Moab into the ground with His foot, like someone stomping straw into a manure pile. There is no question about the final and undignified fate being described. Isaiah does not hold back. Those who trust in the Lord and wait on Him will be saved. Those who refuse to trust in the Lord will experience His judgment. There is no third category of humanity (John 3:16–18, 36).
