I am wondering about the logic behind some translations including the word "first" in Ephesians 4:9 when other translations do not. For example, the KJV/NKJV include the word "first".
Ephesians 4:9 (Now that he ascended, what is it but that he also descended first into the lower parts of the earth? (KJV)
However, translations like the ESV and NASB do not include the word "first".
Ephesians 4:9 (In saying, “He ascended,” what does it mean but that he had also descended into the lower regions, the earth? (ESV)
Ephesians 4:9 (Now this expression, “He ascended,” what does it mean except that He also had descended into the lower parts of the earth? (NASB)
So, what is the reasoning behind the KJV/NKJV using the word "first" in Ephesians 4:9, when most other translations do not. And apart from the KJV/NKJV, which translations include the word "first"?
