הִמּ֧וֹל ׀ יִמּ֛וֹל יְלִ֥יד בֵּֽיתְךָ֖ וּמִקְנַ֣ת כַּסְפֶּ֑ךָ וְהָיְתָ֧ה בְרִיתִ֛י בִּבְשַׂרְכֶ֖ם לִבְרִ֥ית עוֹלָֽם׃
Tutuliin nga ang ipinanganak sa iyong bahay at ang binili ng iyong salapi; at ang aking tipan ay magiging nasa inyong laman bilang isang tipang walang-hanggan.

המול ימול יליד ביתך HE THAT IS BORN IN THY HOUSE MUST NEEDS BE CIRCUMCISED — Here the statement that one born in the house must be circumcised is repeated but it does not say “after eight days” as in 5:12, thus teaching you that there are some cases of those “born in the house” who have to be circumcised on the first day of birth, as is explained in Treatise Sabbath (Shabbat 135b).

בבשרכם; the word בשר is a euphemism for the reproductive organ of the male, as for instance in Ezekiel 16,26 גדלי בשר, "with outsized male member." Or, Leviticus 5, 2-3 זב מבשר, "an uncontrolled seminal emission from his male organ." There are more examples of the word בשר having that same meaning. Seeing that the organ on which the covenant with G'd is marked is the organ instrumental in ensuring a man's continuity beyond death through the genes of his offspring, it is appropriate that the covenant which represents the eternal intimate and reciprocal relationship of G'd and the Jewish people should be symbolized in this manner.
