Israelites who are truly circumcised according to the scripture are all pretty much circumcised in the same manner. The are four "generations" to the first age of the man, like the four seasons in the full revolution of a year: Autumn, Winter, Spring, and the Summer of your harvest, (hear the parable of the fig tree). These four generations are likened unto four beasts which are the beasts of man, (the fourth beast is dreadful and terrible). And these things we know because the scripture cannot be broken, and in the new covenant every man will die for his own sins; the fathers shall not be put to death for the sons, neither shall the sons be put to death for the fathers: every man shall be put to death for his own sin, (Deut 24:16), and yet we read also in the Torah the statements of Gen 15:16, Exo 20:5, 34:7, Num 14:18, and Deut 5:9. So with these statements and what is written in Eze 18:2, 3, 4, and Jer 31:27, 28, 29, 30, 31, (both of these passages being new covenant language), there can be only one resolution if all of it be true; and that is that there must be four generations to the one selfsame man, (for the scripture cannot be broken and all of it must be held true and without contradiction).
Proverbs 30:11-14
11 There is a generation [1] that curses their father and does not bless their mother.
12 There is a generation [2] that are pure in their own eyes and yet is not washed from their filthiness.
13 There is a generation, [3] O how lofty are their eyes! and their eyelids are lifted up.
14 There is a generation, [4] whose teeth are as swords, and their jaw teeth as knives, [Dan 7:7, "great iron teeth"] to devour the poor from off the earth, and the needy from among men.
These four generations are like a lion or a lioness, (Septuagint version of Dan 7:4), a she-bear robbed of her cubs, a leopard or a leopardess, and a fourth wild beast dreadful and terrible, with great iron teeth like swords and jaw teeth as knives. Moreover the fourth beast has a full-on heart of stone like Pharaoh that great dragon in the midst of his rivers; and over that heart of stone develops a caul or chestplate of iron so that it ends up taking these four beasts just to cleave open the hardened chestplate of iron, (for Elohim uses our own
wild beasts against us to bring us into true repentance while at the same time putting the beasts of man into subjection, (the flesh, "their lives are prolonged for a season and a time")). And at the consummation of the first "age" or "dispensation" of the man, in his "fourth generation" which is his fourth beast; the iron chestplate of the caul over the heart is rent asunder and cleaved open so that the heart may be removed for circumcision by the Master, the Minister of the circumcision, (Hos 13:6-11, Dan 7:2-11, Rom 14:10, 2Cor 5:10, Rev 13:2). In that day Zerubbabel himself will remove the headstone heart of stone from the cavity of the wild beast of the man; and there will be shouts of "Grace! Grace to him!", (Zec 4:7, 2Cor 12:1-8, 9). And from that time time shall be no more; and so shall the holy ones ever be with the Master in the age which is to come, (and in this age they cannot die anymore; for they are as the angels, and are sons of Elohim, being sons of the resurrection, Luke 20:36).
