Genesi 27:29

Let people serve thee, and nations bow down to thee: be lord over thy brethren, and let thy mother's sons bow down to thee: cursed [be] every one that curseth thee, and blessed [be] he that blesseth thee.

Ver. 29. Let thy mother's sons bow down to thee.] That is, thy brethren; which are therefore denominated from the mother, quod certior est a matre progenies, quam a patre, saith an interpreter. a But this blessing is pronounced in a higher style than ordinary: therefore sentences are doubled, and that kind of speech is here used which, with us, is either poetical, or not far from it.
