Keturah rescued from certain death in the desert by Ishmael, she was brought to Abraham's dwelling to be nursed back to health. Abraham married Keturah and six sons were born to them, some having scripture references inferring they had providential purposes.
Abraham was over one hundred and forty years old when the six sons were born.

One of many problems they had to work through.

Keturah's sons were educated sufficiently and had vocations to get them started in life. When would be the right time to send them away? If he sent them east where he hoped they would go, how far east would they go? And would they stay away?
