“Then again Abraham took a wife, and her name was Keturah.”
King James Version (KJV)
25:1 Five and thirty years Abraham lived after the marriage of Isaac, and all that is recorded concerning him during that time lies here in a very few verses: we hear no more of God's extraordinary appearances to him, or trials of him; for all the days even of the greatest saints are not eminent days, some slide on silently, and neither come nor go with observation: such were these last days of Abraham. We have here an account of his children by Keturah, another wife, which be married after the death of Sarah. He had buried Sarah, and married Isaac, the two dear companions of his life, and was now solitary; his family wanted a governess and it was not good for him to he thus alone; he therefore marries Keturah, probably the chief of his maid servants, born in his house, or bought with money. By her he had six sons, in whom the promise made to Abraham concerning the great increase of his posterity was in part fulfilled. The strength he received by the promise still remained in him, to shew how much the virtue of the promise exceeds the power of nature.
