SEV Biblia, Chapter 1:30
que como yo te he jurado por el SEÑOR Dios de Israel, diciendo: Tu hijo Salomón reinará después de mí, y él se sentará en mi trono en lugar mío; que así lo haré hoy.
John Gill's Bible Commentary
Ver. 30. Even as I sware unto thee by the Lord God of Israel , etc.] And so owns and confirms the truth of what Nathan had suggested to Bathsheba, and she had asserted, ( 1 Kings 1:13,17); saying, assuredly Solomon thy son shall reign after me, and he shall sit upon my throne in my stead ; this was the substance of the oath: even so will I certainly do this day ; perform this oath, and set Solomon on the throne.
Matthew Henry Commentary
Verses 11-31 - Observe Nathan's address to Bathsheba. Let me give thee counsel how to save thy own life, and the life of thy son. Such as this is the counse Christ's ministers give us in his name, to give all diligence, not onl that no man take our crown, Re 3:11, but that we save our lives, eve the lives of our souls. David made a solemn declaration of his fir cleaving to his former resolution, that Solomon should be his successor. Even the recollection of the distresses from which the Lor redeemed him, increased his comfort, inspired his hopes, and animate him to his duty, under the decays of nature and the approach of death.
