Isaiah 51:15

But I am the Lord thy God that divided the sea, whose waves roared,.... Referring to the dividing of the Red sea by a violent wind, at which time the waves of it doubtless roared till they were made

But I am the LORD thy God, that divided the sea, whose waves roared: The LORD of hosts is his name. I (am) the Lord thy God, that divided the sea, whose waves roared - the Red Sea.

Isaiah 51:15 But I [am] the LORD thy God, that divided the sea, whose waves roared: The LORD of hosts [is] his name.Ver. 15. For I am the Lord thy God, that divided the sea.] Or, I the Lord thy God am he that stilleth the sea when the waves of it roar; how much more then can I curb and control the rage of man! "Surely," saith David, "the wrath of man shall praise thee: the remainder of wrath shalt thou restrain"; where the Septuagint have it, It shall keep holiday to thee, εωρταζεισοι.

(15) But I am . . .—Better, Seeing that I am. The fact which follows is not contrasted with that which precedes, but given as its ground. The might of Jehovah is seen in the storm-waves of the sea. It is seen not less in the fall and rise of empires.

Ch. Isaiah 51:1-16. Encouragements addressed to true IsraelitesThe strain of consolation, which was interrupted by the soliloquy of the Servant at ch. Isaiah 50:4, is now resumed, and is continued till we reach the fourth and last of the Servant-passages, Isaiah 52:13 to Isaiah 53:12. Throughout this long passage (Isaiah 51:1 to Isaiah 52:12) the prophet’s thoughts are occupied with the near prospect of deliverance, and his high-strung emotion finds vent in a series of short impassioned oracles, mostly of a lyrical character. These may be divided into two groups, each consisting of three oracles. While those of the second group (Isaiah 51:17 to Isaiah 52:12) are addressed to the prostrate and desolate Zion, the first (Isaiah 51:1-16) contains words of cheer to the faithful but timid hearts in whom the prophet’s message had found an entrance. This section shews some points of contact with the preceding descriptions of the Servant, and the line of thought was probably influenced by the last of these, in Isaiah 50:4-9. The contents of the section are as follows:— i. Isaiah 51:1-8. A glowing and animated appeal to the believing exiles to put away the fears and misgivings which hinder their full acceptance of the promise of salvation. The thrice-repeated “Hearken to me” (see, however, on Isaiah 51:4) indicates a division into three strophes. (1) The first draws a lesson of encouragement from the example of the solitary patriarch Abraham, who by the blessing of Jehovah became the progenitor of a great nation. Let the true-hearted believers, therefore, take courage, in spite of the fewness of their number, for the same blessing rests on them, and will transform the waste places of Zion into a scene of joy and gladness (Isaiah 51:1-3). (2) The next strophe directs the hope of the loyal Israelites to the glorious future that belongs to those who wait for Jehovah’s salvation; though heaven and earth pass away that world-wide salvation is imperishable and eternal (Isaiah 51:4-6). (3). The last strophe, re-echoing one of the voices of the Prologue (Isaiah 40:6-8), reminds the exiles that the reproach they fear is that of frail and short-lived mortals, while the salvation they hope for endures for ever. ii. Isaiah 51:9-10. Here for a moment the prophetic discourse is interrupted by a magnificent apostrophe to the “arm” of Jehovah. The speakers are most probably those to whom the previous words were addressed. As if all their doubts had been swept away by the impressive appeals to which they have listened, their impatience breaks forth in this impetuous challenge to Jehovah to reveal His power as in the days of old. (Isaiah 51:11 has been inserted from ch. Isaiah 35:10.) iii. Isaiah 51:12-16. The Divine voice is again heard (in answer to the people’s prayer). Since their comforter is Jehovah Himself, the Creator of heaven and earth, how unreasonable is their craven fear of their cruel oppressors! (Isaiah 51:12-13). Towards the close, however, the connexion becomes very obscure (see the notes).

But I am the Lord thy God - In order to show them that he was able to save them, God again refers to the fact that he had divided the sea, and delivered their fathers from bondage and oppression.

14-16. The captive exile — One bowed down under the burden of captivity, which may be general, but more likely is here local, the captivity in Babylon. Hasteneth… loosed — Set free.
