Philo Judaeus De Virtutibus 116

And thus the lawgiver pouring precept after precept into ready and obedient ears, enjoins humanity. ¹ Moreover, even if any beasts of burden belonging to the enemy while bearing burdens are oppressed by the weight, and fall down beneath them, he commands that the people should not pass them by, but that they should lighten their burdens and raise them up, teaching them thus by remote examples not to be delighted at the unexpected misfortunes even of those who hate them, knowing that to rejoice in the disasters ^{2 3} of others is a malignant and odious passion, both akin to and contrary to envy; akin to it, because each of these feelings proceeds from passion, and because they approach near to, and one may almost say reciprocate, one another; but contrary, because the one feeling causes grief at the good fortune of another, and the other excites joy at the misfortunes of one’s neighbour.
