MIGHT, n.² [mite; Sax. might, meht; G. macht; D. Sw. and Dan. magt; from the root of may, Sax. magan, to be able; Sans. mahat, strong. See May.]

1. Strength; force; power; primarily and chiefly, bodily strength or physical power; as, to work or strive with all one's might. There shall be no might in thy hand. Deut. xxviii.
2. Political power or great achievements. The acts of David with all his reign and his might. 1 Chron. xxix. 1 Kings. xv.
3. National strength; physical power or military force. We have no might against this great company that cometh against us. 2 Chron. xx.
4. Valor with bodily strength; military prowess; as, men of might. 1 Chron. xii.
5. Ability; strength or application of means. I have prepared with all my might for the house of my God. 1 Chron. xxix.
6. Strength or force of purpose. Like him was no king that turned to the Lord with all his might. 2 Kings xxiii.
7. Strength of affection. Thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might. Deut. vi.
8. Strength of light; splendor; effulgence. Let them that love him be as the sun when he goeth forth in his might. Judges v. Shakspeare applies the word to an oath. “An oath of mickle might.” This application is obsolete. We now use strength or force; as, the strength or force of an oath or covenant. With might and main, with the utmost strength or bodily exertion; a tautological phrase, as both words are from the same root, and mean the same thing.
