Psalms 18:25-26

18:25 You prove to be loyal to one who is faithful;

you prove to be trustworthy to one who is innocent.

18:26 You prove to be reliable to one who is blameless,

but you prove to be deceptive to one who is perverse.

Psalms 50:18

50:18 When you see a thief, you join him;

you associate with men who are unfaithful to their wives.
