Jewish Publication Society 1917 · Berean Standard Bible
And I have said unto thee: Let My son go, that he may serve Me; and thou hast refused to let him go. ‘Behold, I will slay thy first-born.’
and I told you to let My son go so that he may worship Me. But since you have refused to let him go, behold, I will kill your firstborn son!’”
