Pseudo-Barnabas

Learn fully then, children of love, concerning all things, for Abraham, who first circumcised, did so looking forward in the spirit to Jesus and had received the doctrines of the three letters. For it says, “Abraham circumcised from his household eighteen men and three hundred.” What then was the knowledge that was given to him? Notice that he first mentions the eighteen, and after a pause the three hundred. The eighteen is I (= 10) and H (= 8)—you have Jesus—and because the cross was destined to have grace in the T he says “and three hundred.” So he indicates Jesus in the two letters and the cross in the other. He knows this who placed the gift of his teaching in our hearts.

[Burnt offerings] he accordingly did away with, so that the new law of our Lord Jesus Christ might be without restraining yoke and without manmade offering. Again he says to them, “Did I command your fathers when they came out of the land of Egypt to offer me burnt offerings and sacrifices? Rather I did command them this: Let none of you cherish evil in his heart against his neighbor, and do not love a false oath.” We ought therefore to understand, if we are not senseless, the kindly intention of our Father, for he speaks to us, desiring us not to err like them but to seek how to make our offering to him. To us he accordingly speaks thus: “A contrite heart is a sacrifice to the Lord; an odor of sweetness to the Lord is a heart which glorifies its maker.” We ought, therefore, to watch carefully after our salvation, brothers, lest the evil one, sneaking in among us deceitfully, push us away from our life.
