Genesis 27:9

It is observable, that as Jacob deceived his father by a kid, so his sons deceived him by the same creature, Genesis 37:31. I will make them savoury meat, out of their most tender and delicate parts; wherewith it was not difficult to deceive Isaac, partly because of the likeness of the flesh, especially being altered by convenient sauce; and partly because the same old age which had dimmed Isaac's sight had also dulled his other senses.
