It is important to note that the words "when" and "am" in this verse do not appear in the original Hebrew. They were inserted later into the text of the King James. Thus, I believe Elijah is saying to Elisha, "If you see me as being taken from you."
Mahalagang tandaan na ang salitang "kung" at "ako" sa versikulong ito ay hindi nasusulat sa pinagmulang Hebreo. Sila ay isiningit ng bandang huli sa texto ng "King James".
