Who had the first god-ordered circumcision?

Abraham and his sons were the first Semites to be circumcised, but the practise was common in Egypt and Canaan thousands of years earlier

Sorry, it is all BULL $hit contrived by human's. There is zero creator of the universe content in that covenant crap.

Penis parts cutting of babies was done as a marking, tribal or even slave. The Egyptians did it some, well before the Hebrews. However, sexual sacrifice (a religious practice) was also an early aspect of this creepy thing. The sacrifice of erogenous tissue of a victim (a baby) is better than human sacrifice, but it is still barbaric BS contrived by HUMANS.

its almost impossible to say exactly who was the very first

see why:

Gen 17:23 On that very day Abraham took his son, Ishmael, and every male in his household, including those born there and those he had bought. Then he circumcised them, cutting off their foreskins, just as God had told him.

Gen 17:24 Abraham was ninety-nine years old when he was circumcised,

Gen 17:25 and Ishmael, his son, was thirteen.

Gen 17:26 Both Abraham and his son, Ishmael, were circumcised on that same day,

Gen 17:27 along with all the other men and boys of the household, whether they were born there or bought as servants. All were circumcised with him.
