The sea is the symbol of restless and indomitable energy, chafing against all resistance, and dashing to pieces the works whereby man endeavors to restrain its fury. Yet God has imposed upon it laws which it must obey, and keeps it in its appointed place, not by barriers of iron but by a belt of sand. Modern science has shown that the resisting power of sand is enormous. A wave which would shatter rocks fails powerless upon sand.

Can they not prevail - The opposite of "thou couldest" Jeremiah 3:5. The sea, the mightiest of God's works, cannot prevail, cannot break God's laws, because He has not endowed it with free-will. Man, physically impotent, can prevail, because, being made in God's image, he is free.

Which have placed the sand for the bound of the sea - What can I not do, who confine the sea, that enormous mass of waters, and prevent it from overflowing the earth; not by immense mountains and rocks, but by the sand, no particle of which is in cohesion with another? The most tremendous waves cannot displace nor pass over this simple barrier.

Fear ye not me? saith the Lord,.... They did not fear the Lord, and this is a reproof to them for the want of it, which is a reproof of their ignorance and folly; for the fear of the Lord is the beginning of wisdom, Proverbs 9:10, and where that is there is true wisdom; but, where it is not, there is nothing but ignorance and stupidity:

will ye not tremble at my presence? or "face"; his wrath and anger, justly resenting their carriage to him. The Targum is,

"from before my Word;''

the essential Word, his Son: or, "will ye not be in pain?" as a woman in travail; as Kimchi observes the word (b) signifies:

which have placed the sand for the bound of the sea by a perpetual decree, that it cannot pass it. This is a very wonderful thing in nature, that the earth and sea, being spherical, and making one terraqueous globe, and the waters of the sea being higher than the earth, should be so bounded and restrained, by the power and providence of God, as not to overflow the earth, and that by means of the sand, which is penetrable, flexible, and movable; and yet this is set as a bound, and by the decree of God remains firm and stable, and that for ever, so that the sea cannot bear it down, go through it, or over it:

and though the waves thereof toss themselves, yet can they not prevail; though they roar, yet can they not pass over it; even when the sea is the most tumultuous and raging. This is an instance of the mighty power of God, and carries in it an argument and reason why he should be feared; and yet such was the stupidity of this people, that though they saw this with their eyes, the sea and the tossings of it, and the sand set as a bound to it, and an effectual one, and heard the roarings and ragings of the waves of it in vain; yet they feared not the Lord that did all this; and so showed themselves more stupid and disobedient than the sea and its waves, which obeyed their Maker, though destitute of sense and reason; see Job 26:10.

(b) "Significantissima impimis vox est" "quae significat ita angi ut parturiens", Schmidt.

Fear ye not me? saith the LORD: will ye not tremble at my presence, which 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?

5:22 The sand - That need not make rocks for walls unto it, but can give a check to it by so small a matter as the sand.

22. sand-Though made up of particles easily shifting about, I render it sufficient to curb the violence of the sea. Such is your monstrous perversity, that the raging, senseless sea sooner obeys Me, than ye do who profess to be intelligent [Calvin], (Job 26:10; 38:10, 11; Pr 8:29; Re 15:4).

5:19-31 Unhumbled hearts are ready to charge God with being unjust in their afflictions. But they may read their sin in their punishment. If men will inquire wherefore the Lord doeth hard things unto them, let them think of their sins. The restless waves obeyed the Divine decree, that they should not pass the sandy shores, which were as much a restraint as lofty mountains; but they burst all restraints of God's law, and were wholly gone into wickedness. Neither did they consider their interest. While the Lord, year after year, reserves to us the appointed weeks of harvest, men live on his bounty; yet they transgress against him. Sin deprives us of God's blessings; it makes the heaven as brass, and the earth as iron. Certainly the things of this world are not the best things; and we are not to think, that, because evil men prosper, God allows their practices. Though sentence against evil works is not executed speedily, it will be executed. Shall I not visit for these things? This speaks the certainty and the necessity of God's judgments. Let those who walk in bad ways consider that an end will come, and there will be bitterness in the latter end.
