(Chapter XXXI, verses 7 and 8) And your father deceived me and changed my wages ten times, and God did not allow him to harm me. If he said, 'Your wages will be the spotted flock,' then every flock was born spotted. And if he said, 'Your wages will be the solid-colored flock,' then every flock was born solid-colored. Because of this, he changed my wages ten times. The Seventy Interpreters have stated, driven by some unknown opinion, that 'moni' in the Hebrew language means 'number' rather than 'lambs.' Finally, the meaning is further confirmed by the fact that Laban always changed the condition of each offspring. If he saw mixed livestock being born, he would say after the birth, 'I want mixed offspring in the future.' Again, when he saw single-colored animals being born (because Jacob had heard this, he did not place rods in the canals), he would say that the future offspring should be of a single color for him. And what more? Laban changed the condition of his flock or Jacob up to ten times. And whatever color he had intended to be born as, it turned into the opposite color. And so that no one may think that in ten years twenty births are incredible, read Virgil (Georg. II), in which it is said:
The pregnant cattle twice. However, it is said that the nature of Italian and Mesopotamian sheep is the same.
[AD 420] Jerome on Genesis 31:7-8
The pregnant cattle twice. However, it is said that the nature of Italian and Mesopotamian sheep is the same.
