Thematic Bible: The covenant of circumcision

And it came to pass that, when Abram was ninety and nine years old, Yahweh appeared unto Abram, and said unto him, I, am GOD Almighty, - Walk, thou before me and become thou blameless: That I may set my covenant betwixt me and thee, And may multiply thee, exceedingly. And Abram fell on his face, - and God spake with him, saying: read more.
As for me, lo! my covenant is with thee, - So shalt thou become - father of a multitude of nations; And thy name shall no more be called Abram, - but thy name shall become Abraham, for father of a multitude of nations, have I appointed thee; And I will make thee fruitful, exceedingly, and grant thee to be nations, - Yea kings, out of thee, shall come forth; And I will confirm my covenant betwixt me and thee and thy seed after thee to their generations for an age-abiding covenant, - to become to thee a God, and to thy seed after thee; And I will give to thee and to thy seed after thee the land of thy sojournings - all the land of Canaan, for an age-abiding possession - And I will be to them a God. And God said unto Abraham, But, as for thee, my covenant, must thou keep, thou and thy seed after thee, to their generations: - This, is my covenant which ye shall keep, betwixt me and you, and thy seed after thee, - To circumcise to you every male: So shall ye be circumcised in the flesh of your foreskin, - So shall it become a sign of a covenant, betwixt me and you. And he that is eight days old, shall be circumcised to you every male to your generations, - he that is born of the house, and he that is bought with silver of any son of a stranger, who is, not of thy seed, He must surely be circumcised, born of thy house or bought with thy silver, - So shall my covenant be in your flesh for an age-abiding covenant. But, as for the uncircumcised male who shall not be circumcised in the flesh of his foreskin, - that person shall be cut off from among his people, - my covenant, hath he made void.
