מדרש אויף בראשית 24:5

“The servant said to him: Perhaps the woman will not wish to follow me to this land; shall I return your son to the land from which you departed?” (Genesis 24:5).
“The servant said to him” – that is what is written: “A trader, scales of deceit are in his hand; he loves to exploit [laashok ahev]” (Hosea 12:8). “A trader [kenaan]” – this is Eliezer,³⁰The Sages always identify the servant in our passage as Eliezer, who is mentioned in Genesis 15:2. [who was a Canaanite]. “Scales of deceit are in his hand” – because he was sitting and deliberating about his daughter: Is she worthy [to marry Isaac] or is she not worthy? Laashok ahev – to exploit the beloved one [ahuvo] of the world, that being Isaac. He said: ‘“Perhaps [the woman] will not wish [to follow me]” and I will give him my daughter [in marriage].’ He [Abraham] said: ‘You are cursed³¹“Cursed be Canaan” (Genesis 9:25). and my son is blessed. The cursed do not cleave to the blessed.’
