1 Chronicles 17:27 - Joseph Benson’s Commentary on the Old and New Testaments

Let it please thee to bless the house of thy servant He is therefore encouraged to ask a blessing because God had intimated to him that he had blessings in store for him and his family; thou blessest, O Lord And therefore unto thee shall all flesh come for a blessing: unto thee do I come for the blessing promised to me. And he is therefore earnest for the blessing, because those whom God blesseth are truly and eternally blessed. Thou blessest, and it shall be blessed Men can but beg the blessing, it is God that commands it; what he designs, he effects; what he promises, he performs; saying and doing are not two things with him. Nay, it shall be blessed for ever His blessings shall not be revoked from the faithful, and the benefits conferred by them are such as will survive time and days. David's prayer concludes as God's promise did, (1 Chronicles 17:14,) with that which is for ever. God's word looks at things eternal, and so should our desires and hopes.
