And Elias said to Achab: Go up, eat, and drink: for there is a sound of abundance of rain.

And Elijah saith to Ahab, 'Go up, eat and drink, because of the sound of the noise of the shower.'

Then Elijah said to Ahab, Up! take food and drink, for there is a sound of much rain.

And Elijah said to Ahab, 'Get up, eat and drink; for there is the sound of a heavy rain.'

And Elijah said to Ahab "Ascend; eat and drink. For there is the sound of an abundance of rain."

Get thee up, eat and drink - Ahab had descended the hill-side with Elijah, and witnessed the slaughter of the priests. Elijah now bade him ascend the hill again, and partake of the feast which was already prepared, and which always followed upon a sacrifice.
There is a sound of abundance of rain - Either the wind, which in the East usually heralds rain, had begun to rise, and sighed through the forests of Carmel - or perhaps the sound was simply in the prophet's ears, a mysterious intimation to him that the drought was to end, and rain to come that day.

Get thee up, eat and drink - It appears most evidently that Ahab and the prophet were now on good terms, and this is a farther evidence that the slaying of the false prophets was by the king's consent.

And Elijah said unto Ahab, get thee up,.... From the brook and valley where the execution of the prophets had been made; either up to his chariot, or to the tent or pavilion erected on the side of the mount, where the whole scene of things was transacted;
eat and drink; which he had no leisure for all the day, from the time of the morning sacrifice to the evening sacrifice, which was taken up in attending to the issue of the several sacrifices; but now he is bid to eat and refresh himself, and that in token of joy and gladness, as became him, both for the honour of the true God, which had been abundantly confirmed, and for the near approach of rain, of which he assures him:
for there is a sound of abundance of rain; the wind perhaps began to rise, and blow pretty briskly, which was a sign of it (f); besides, according to the Tyrian annals (g), there were loud claps of thunder at this time, at least when the heavens became very black, as in 1-Kings 18:45.
(f) "Fit fragor, hinc densi----nimbi", Ovid. Metamorph. l. 1. Fab. 8. v. 269. (g) Apud Joseph, Antiqu. l. 8. c. 13. sect. 2.

Israel, being so far reformed as to acknowledge the Lord to be God, and to consent to the execution of Baal's prophets, was so far accepted, that God poured out blessing upon the land. Elijah long continued praying. Though the answer of our fervent and believing supplications does not come quickly, we must continue earnest in prayer, and not faint or give over. A little cloud at length appeared, which soon overspread the heavens, and watered the earth. Great blessings often arise from small beginnings, showers of plenty from a cloud of span long. Let us never despise the day of small things, but hope and wait for great things from it. From what small beginnings have great matters arisen! It is thus in all the gracious proceedings of God with the soul. Scarcely to be perceived are the first workings of his Spirit in the heart, which grow up at last to the wonder of men, and applause of angels. Elijah hastened Ahab home, and attended him. God will strengthen his people for every service to which his commandments and providence call them. The awful displays of Divine justice and holiness dismay the sinner, extort confessions, and dispose to outward obedience while the impression lasts; but the view of these, with mercy, love, and truth in Christ Jesus, is needful to draw the soul to self-abasement, trust, and love. The Holy Spirit employs both in the conversion of sinners; when sinners are impressed with Divine truths, they should be exhorted to set about the duties to which the Saviour calls his disciples.

Elijah then called upon the king, who had eaten nothing from morning till evening in his eagerness to see the result of the contest between the prophet and the priests of Baal, to come up from the brook Kishon to the place of sacrifice upon Carmel, where his wants were provided for, and to partake of meat and drink, for he (Elijah) could already hear the noise of a fall of rain. קול is without a verb, as is often the case (e.g., Isaiah 13:4; Isaiah 52:8, etc.); literally, it is the sound, the noise. After the occasion of the curse of drought, which had fallen upon the land, had been removed by the destruction of the idolatrous priest, the curse itself could also be removed. "But this was not to take place without the prophet's saying it, and by means of this gift proving himself afresh to be the representative of God" (O. v. Gerlach).

Get up - From the river, where he had been present at the slaughter of Baal's priests, to thy tent: which probably was pitched on the side of Carmel. Eat, &c. - Take comfort, and refresh thyself: for neither the king, nor any of the people could have leisure to eat, being wholly intent upon the decision of the great controversy. For there is, &c. - The rain is as certainly coming, as if you heard the noise which it makes.
