The Lord hath sworn that the Lord will have war with Amalek, etc. - This is no translation of the words כי יד על כס יה מלחמה ki yad al kes yah milckamah, which have been variously rendered by different translators and critics; the most rational version of which is the following: Because the hand of Amalek is against the throne of God, therefore will I have war with Amalek from generation to generation. This gives a tolerably consistent sense, yet still there is considerable obscurity in the passage. Houbigant, a most judicious though bold critic, supposes that, as יהוה נסי Jehovah-nissi, Jehovah my ensign, was spoken of immediately before, כס kes, a throne, in this verse, is an error of some transcriber for נס nes, an ensign, which might be readily occasioned by the great similarity between the כ caph and the נ nun. He thinks farther that the two letters יה yah, which are supposed to be here a contraction of the word יהוה Yehovah, are separated, the י yod from the נס nes, which should be written נשי nissi, and the ה he, from מלחמה milchamah, which should be written המלחמה hammilchamah, and then the whole verse will run thus: For the hand shall be upon the ensigns of war unto the Lord, against Amalek for ever, i.e., God makes now a declaration of war against the Amalekites, which shall continue till their final destruction. The conjecture of Mr. Julius Bate, in his Literal Translation of the Pentateuch, deserves attention. He supposes that, as כס cos signifies a cup, and a cup is emblematically used for wrath, on one of the stones of the altar, mentioned in the preceding verse, a hand holding a cup was sculptured, this being a memorial, according to the custom of hieroglyphical writing, that the Lord would continue the cup of wrath, portending continual war, against Amalek for ever. I prefer Houbigant's exposition.

1. This first victory of Israel must have inspired them with a considerable measure of confidence in God, and in his servant Moses. Though God alone could give them the victory, yet it was necessary to show them that it was by the influence of Moses they got it. Moses could not deliver Amalek into their hands; yet if Moses did not continue to hold up his hands, i.e., to pray, Amalek must prevail. God, therefore, wrought this work in such a way as to instruct the people, promote his own glory, and secure the true honor of his servant. The Divine Being always performs the greatest number possible of ends, by the fewest and simplest means. In every work of God there is as much of wisdom and economy, as there is of sovereign uncontrolled power.

2. It is not probable that the people whom Joshua chose out to lead against Amalek were unarmed; and we have already seen that it is not at all likely that they came armed out of Egypt. And as the whole circumstances of this case show that those who fought against the Amalekites were properly equipped for the fight, we may then safely presume that they got their arms from the Egyptians, whose bodies were thrown on the shore after having been overwhelmed in the Red Sea. Thus, what was a judgment in the one case, was a most gracious providence in the other. Judgment on God's foes is mercy to his friends.

3. Of the efficacy of prayer we have already had the most striking examples. He who has the spirit of prayer, has the highest interest in the court of heaven; and the only way to retain it, is to keep it in constant employment. Apostasy begins in the closet: no man ever backslid from the life and power of Christianity who continued constant and fervent, especially in private prayer. He who prays without ceasing is likely to rejoice evermore.

because or because the hand of Amalek is against the throne of the Lord, therefore, the Lord. Heb. the hand upon the throne of the Lord.

Isaiah 66:1 Thus said the LORD, The heaven is my throne, and the earth is my footstool: where is the house that you build to me?...

Acts 7:49 Heaven is my throne, and earth is my footstool: what house will you build me? said the Lord: or what is the place of my rest?

Text.--And it came to pass, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. But Moses's hands were heavy, and they took a stone, and put it under him, and he sat thereon: and Aaron and Hur stayed up his hands, the one on the one side and the other on the other side: and his hands were steady until the going down of the sun. And Joshua discomfited Amalek and his people with the edge of the sword.--Exodus xvii. 11-13. You who read your Bibles will …

"Because the Carnal Mind is Enmity against God, for it is not Subject to the Law of God, Neither Indeed Can Be. "
Rom. viii. 7.--"Because the carnal mind is enmity against God, for it is not subject to the law of God, neither indeed can be." Unbelief is that which condemns the world. It involves in more condemnation than many other sins, not only because more universal, but especially because it shuts up men in their misery, and secludes them from the remedy that is brought to light in the gospel. By unbelief I mean, not only that careless neglect of Jesus Christ offered for salvation, but that which is the …

To Augustine, Bishop of the Angli [136] . Gregory to Augustine, &c. Glory to God in the highest, and on earth peace to men of good will (Luke ii. 14); because a grain of wheat, falling into the earth, has died, that it might not reign in heaven alone; even He by whose death we live, by whose weakness we are made strong, by whose suffering we are rescued from suffering, through whose love we seek in Britain for brethren whom we knew not, by whose gift we find those whom without knowing them we sought. …
