Genesis 25:1 vs 1Chronicles 1:32? Keturah: Wife or Concubine?

A MUSLIM Ayehd Miguel is CONFUSED about Genesis 25:1 and 1Chronicles 1:32. (See picture)

Genesis 25:1
Abraham took ANOTHER WIFE, whose name was Keturah.

1Chronicles 1:32
 The sons of Keturah, Abraham's CONCUBINE: she bore Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. The sons of Jokshan: Sheba and Dedan.

Ayedh is CONFUSED with the WORDS "ANOTHER WIFE" and "CONCUBINE."

For HIM, these have DIFFERENT MEANINGS.

HERE is OUR RESPONSE to HIM:

Ayehd Miguel, this is just ANOTHER EXAMPLE of Muslims CRITICIZING what they DO NOT UNDERSTAND.

The Hebrew term for "wife" in Genesis 25:1 is ISHSHAW which generally refers to a WOMAN.

In the context of Genesis 25:1, this ISHSHAW or WOMAN was taken by Abraham as his WIFE.

So, Genesis 25:1 only relates of how Abraham took ANOTHER WOMAN AFTER the death of his wife, Sarah.

The CONCUBINE in 1Chronicles 1:32 is ALSO a "WOMAN" whom Abraham took as his WIFE.

Keturah is described as a "concubine" because she is ANOTHER WIFE even though Abraham's first wife was already dead.

So, Genesis 25:1 ang 1Chronicles 1:32 are talking of ONE and the SAME THING: A WOMAN TAKEN as ANOTHER WIFE.

There should be NO CONFUSION in that.

Perhaps, MUSLIMS SHOULD STUDY FIRST BEFORE THEY CRITICIZE.
