John Trapp on Job 8:5

Verſe 5. If thou wouldſt ſeek unto God betimes] If warned by the evil end that befell thine unhappy children, thou wouldſt early and earneſtly ſeek unto God for mercy, for which purpoſe it may ſeem that thy life hath been graciouſly ſpared, when thy children have been deſtroyed, that thou mightſt be made wiſe at their expence. Such counſel as this is, Eliphaz had given Job before, chap. 5.8.

And make thy ſupplication to the Almighty] Pray for mercy out of free-grace alone, ſo the Hebrew word ſignifieth: plead for pity, ſpeak ſupplications as the poor man doth, Prov 18.23. Be poor in ſpirit, a ſtark beggar and bankrupt, leſſe then the leaſt of all Gods mercies, Gen. 32.10. and in this mind addreſſe thy ſelf to the All-ſufficient, the Cornucopia, the God rich in mercy to all that call upon him, for pardon of thy great ſin in ſtanding out in contention with his Majeſty, and reſiſting his fatherly viſitation.
