Romans 15:4 - Joseph Benson’s Commentary on the Old and New Testaments

For whatsoever things were written aforetime In the Old Testament; were written for our learning As if he had said, Though this may seem to concern David or Christ only, yet it, and all other parts of Scripture, whether containing promises or threatenings, whether speaking of rewards or punishments, were intended to be useful to God's people in after ages; and by this passage in particular, we may learn to bear with the infirmities of others, a matter of great importance in religion; nay, of absolute necessity, considering that we ourselves, and all around us, not excepting the wisest and holiest Christians, are compassed about with infirmity; that through patience and comfort of the Scriptures By learning and exercising such patience as the Scriptures prescribe, especially in bearing with the infirmities of others, and by obtaining those comforts the Scriptures hold forth to us; we might have hope Might be confirmed in our expectation of eternal life, or that through the consolation which God gives us by the Scriptures, we might have patience and a joyful hope.
