Jerome : (Verse 9 and 10.) And Jacob said, O God of my father Isaac, Lord, who said to me, Return to your land and I will bless you: I am less than all your mercies, and all your truth, which you have shown to your servant. For because of what we have done, I am less, something else I do not know, which disturbs the meaning, is contained in the Greek and Latin codices. — Hebrew Questions on Genesis
