John Trapp on Jeremiah 3:5

Ver. 5. Will he reſerve his anger for ever?] Will he not? Nah. 1.2. and is there not good reaſon he ſhould do ſo, ſo long as you ſpeak and do evil things as you can, obſtinately perſiſting in thy ſinful practiſes? He that repenteth with a contradiction (ſaith Tertullian) God will pardon him with a contradiction. Thou repenteſt, and yet continueſt in thy ſins. God will pardon thee, and yet ſend thee to bell: There's a pardon with a contradiction.

As thou couldeſt] i. e. To thine utmoſt. Nolunt ſolita peccare, ſaith Seneca of ſome: they ſtrive to out-ſin themſelves, and others.
