22. And you shall say to Pharaoh, Thus says the Lord, Israel is My son, even My firstborn.
23. And I say to you, Let My son go, that he may serve Me; and if you refuse to let him go, behold, I will slay your son, your firstborn.
24. Along the way at a [resting-] place, the Lord met [Moses] and sought to kill him [made him acutely and almost fatally ill].
25. [Now apparently he had failed to circumcise one of his sons, his wife being opposed to it; but seeing his life in such danger] Zipporah took a flint knife and cut off the foreskin of her son and cast it to touch [Moses'] feet, and said, Surely a husband of blood you are to me!
26. When He let [Moses] alone [to recover], Zipporah said, A husband of blood are you because of the circumcision.
