Genesis 24:3-5

New International Version - UK

³ I want you to swear by the Lord, the God of heaven and the God of earth, that you will not get a wife for my son from the daughters of the Canaanites, among whom I am living, ⁴ but will go to my country and my own relatives and get a wife for my son Isaac.’

⁵ The servant asked him, ‘What if the woman is unwilling to come back with me to this land? Shall I then take your son back to the country you came from?’
