Genesis 25:1-2

Abraham again took a wife, and her name was Keturah. And she bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. (Genesis 25:1, 2 NKJV)

Abraham was 137 years old when Sarah died. I don't know how long it was after that when He got married, but this is a list of six more children! He really became the "Father of Many" as his new name implies. Notice Midian in this list. That is where Moses ran to when he fled Egypt and Jethro, his Father in law, was a priest of Midian. I wonder if they served the same God since they too are children of Abraham. God's promises always come to pass. What has He promised you?
