Proverbs 29:10

Note, 1. Bad men hate their best friends: The blood-thirsty, all the seed of the old serpent, who was a murderer from the beginning, all that inherit his enmity against the seed of the woman, hate the upright; they seek the ruin of good men because they condemn the wicked world and witness against it. Christ told his disciples that they should be hated of all men. Bloody men do especially hate upright magistrates, who would restrain and reform them, and put the laws in execution against them, and so really do them a kindness. 2. Good men love their worst enemies: The just, whom the bloody men hate, seek their soul, pray for their conversion, and would gladly do any thing for their salvation. This Christ taught us. Father, forgive them. The just seek his soul, that is, the soul of the upright, whom the bloody hate (so it is commonly understood), seek to protect it from violence, and save it from, or avenge it at, the hands of the blood-thirsty.
