Charles Spurgeon Commentary Jeremiah 5:22

"Fear ye not me? saith Jehovah: will ye not tremble at my presence, who have placed the sand for the bound of the sea, by a perpetual decree, that it cannot pass it? and though the waves thereof toss themselves, yet can they not prevail; though they roar, yet can they not pass over it." — Jeremiah 5:22 (ASV)
