Genesis 31:2

And Jacob beheld the countenance of Laban, and, behold, it [was] not toward him as before.

Ver. 2. And Jacob beheld the countenance of Laban.] He said little, for shame, but thought the more, and could not so conceal his discontent, but that it appeared in his lowering looks. That which he had parted with in his riches, was, as it were, raked out of his belly; Job 20:15 he had as beloved have parted with his very heart blood. And this was plain to Jacob by his countenance, which had been friendly, smooth, and smiling; but now was cloudy, sad, spiteful. The young men were hot, and could not hold or hide what was in their heart, but blurted it out, and spoke their minds freely. This old fox held his tongue, but could not keep his countenance.
