They were as fed horses in the morning: everyone neighed after his neighbor's wife.
All Commentaries on Jeremiah 5:8 Go To Jeremiah 5
Basil the Great
AD 379
Humanity … did not understand and neglected to follow God and to become like his Creator. And becoming a slave of the passions of the flesh, “he is compared with senseless beasts and is become like them.” Now he is like an amorous horse that neighs after his neighbor’s wife. Now like a ravenous wolf, lying in wait for strangers, but at another time, because of his deceit toward his brother, he makes himself like the villainous fox. Truly, there is excessive folly and beast-like lack of reason that he, made according to the image of the Creator, neither perceives his own from the beginning nor even wishes to understand such great dispensations that were made for his sake. At least, he should learn his own dignity from them, but he is unmindful of the fact, and he throws aside the image of the heavenly, but he has taken up the image of the earthly.
