'Couched' in the Bible

Judah is a lion's whelp; From the prey, my son, thou art gone up: He stooped down, he couched as a lion, And as a lioness; who shall rouse him up?

He couched, he lay down as a lion, And as a lioness; who shall rouse him up? Blessed be every one that blesseth thee, And cursed be every one that curseth thee.

and say, What was thy mother? A lioness: she couched among lions, in the midst of the young lions she nourished her whelps.
