Charles Spurgeon Commentary Isaiah 27

In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, That is to say, He will punish those who are like leviathan; the proudest, the greatest, and the most powerful sinners will not escape divine justice.

God's laws are not, like cobwebs, meant to catch the little flies while the great ones break through, but He will strike leviathan, He will surely punish the mightiest sinners of the earth.

Even leviathan that crooked serpent;

Difficult to approach, difficult to find, he shall not escape the sword of the Lord.

And he shall slay the dragon that is in the sea.

If men should try to hide from God in hell itself, yet he would find them out; there is no possibility that any offender shall escape his all-seeing eye.

Thus the Lord reveals the tenderness of his love to his Church.

Then follows a remarkable passage in which, it seems to me, we have the plan of salvation plainly set out:

1. Here is man at enmity with his Maker.

Men who are at enmity with God little know how terrifying the force of His strength is. They are like dry thorns when the fire catches them, and nothing burns more readily. The bush on the common, when some wild youth sets fire to it, suddenly blazes up, crackles, and is gone; so will it be with the ungodly. God has only to go through them, and they will be destroyed. But now comes a message of mercy.

Or let him take hold of my strength,

This is what the repenting and believing sinner does; he lays hold of Christ; he takes the strength of God to be his defense, and then the strong God, instead of being a terror, becomes a comfort to him.

That he may make peace with me; and he shall make peace with me. He shall cause them that come of Jacob to take root:

Taking root should be well looked after by the Christian. Some professors have no root; they are all leaf and flower, but they have no root, and consequently they soon wither and die. Happy is that man who is rooted and grounded in the faith!
