3That they should circumcise their sons, according to the covenant which He had made with them, and not deviate to the right hand or the left of all the paths which the Lord had commanded us; and that we should keep ourselves from all fornication and uncleanness, [and renounce from amongst us all fornication and uncleanness].
7I implore you, my sons, love the God of heaven And cleave ye to all His commandments.
9But serve ye the most high God, and worship Him continually: And hope for His countenance always, And work uprightness and righteousness before Him, That He may have pleasure in you and grant you His mercy, And send rain upon you morning and evening, And bless all your works which ye have wrought upon the earth, And bless thy bread and thy water, And bless the fruit of thy womb and the fruit of thy land, And the herds of thy cattle, and the flocks of thy sheep.
10And ye will be for a blessing on the earth, And all nations of the earth will desire you, And bless your sons in my name, That they may be blessed as I am.

13And these mingled with each other, and their name was called Arabs, and Ishmaelites.
