Sorry....for some reason this topic has my interest, so I'll post another thought I found odd/funny.
Ishmael was bragging to Isaac one day about his circumcision, telling Isaac that he was only thirteen when it was done to him. (Sounds like a couple of brothers trying to out-boast the other.)Isaac told him more or less, 'what's a little bit of flesh? I'm willing to give my whole body'. This made me think about Jaheshua and the Jews. They liked to brag about their "chosen-ness" by means of their circumcision, yet Jaheshua was willing to offer up his entire Life.
