Charles Spurgeon Commentary Deuteronomy 32:15

"But Jeshurun waxed fat, and kicked: Thou art waxed fat, thou art grown thick, thou art become sleek; Then he forsook God who made him, And lightly esteemed the Rock of his salvation." — Deuteronomy 32:15 (ASV)

But Jeshurun waxed fat, and kicked:

"The little holy nation" – for I suppose that is the meaning of "Jeshurun." It is a diminutive word – "the little religious nation waxed fat. It abounded in prosperity. It grew stout and kicked."

But Jeshurun waxed fat, and kicked: thou art waxen fat, thou art grown thick, thou art covered with fatness; then he forsook God which made him, and lightly esteemed the Rock of his salvation.

Many can endure the trials of adversity who cannot escape the perils of prosperity. Solomon truly said, As the fining pot for silver, and the furnace for gold; so is a man to his praise; and many a man has failed in that time of testing. When you come to be wealthy, to be admired, to receive honour among men, then is the time of your severest trial.

You have grown fat, you have grown thick, you are covered with fatness; then he forsook God who made him, and lightly esteemed the Rock of his salvation.

Alas! alas! alas! they set up calves in Bethel. They turned aside to Ashtaroth, and worshipped the queen of heaven.
