Philo Judaeus De Virtutibus 147

[147] But, nevertheless, the lawgiver neither neglected the safety of the unclean animals, nor did he permit those which were clean to use their strength in disregard of justice, crying out and declaring loudly in express words, if one may say so, to those persons who have ears in their soul, not to injure any one of a different nation, unless they have some grounds for bringing accusations against them beyond the fact of their being of another nation, which is no ground of blame; for those things which are not wickedness, and which do not proceed from wickedness, are free from all reproach. ^{1 2}
