The Instructions Of Commodianus by Commodianus
XXXIX.--Also to the Jews.
Look upon Leah, that was a type of the synagogue, which Jacob received as a sign, with eyes so weak; and yet he served again for the younger one beloved: a true mystery, and a type of our Church. Consider what was abundantly said of Rebecca from heaven; whence, imitating the alien, ye may believe in Christ. Thence come to Tamar and the offspring of twins. Look to Cain, the first tiller of the earth, and Abel the shepherd, who was an unspotted offerer in the ruin of his brother, and was slain by his brother. Thus therefore perceive, that the younger are approved by Christ.
