This and the next verse are much to the same purpose, wherein the prophet, to encourage them to their industrious endeavours, tells them that the Lord had sworn to see to the prosperity of Jerusalem; and he names the hand, to signify his faithfulness, as the giving of our hand notes our fidelity; and arm, to signify his power, the arm of his strength, i.e. his strong arm: these being eminently to be engaged and put forth for his people, he swears by them. Surely I will no more give; or, If I give; a usual aposiopesis; an abrupt form of swearing, implying something of an imprecation, as great as can be expressed: q.d. Never account me faithful or almighty, if I accomplish not this. The sons of the stranger: see Isaiah 61:5. Shall not drink thy wine, for the which thou hast laboured: the meaning is, That meat, and drink, and all necessaries that thou hast laboured for, the Babylonians took away from thee; but now it shall be so no more, he will not give thee up to the will of thine enemies.
