In this story; Elisha asks God for a double portion of the blessing that He poured out on the Prophet Elijah.
The idea of a double portion was not to ask for twice as much as Elijah had, but to ask for the portion that went to the firstborn son, as in Deuteronomy 21:17. Elisha asked for the right to be regarded as the successor of Elijah, as his firstborn son in regard to ministry. Yet Elisha had already been designated as Elijah’s successor (1 Kings 19:19). This was a request for spiritual power to fulfill the calling he already received. Interestingly, Scripture records exactly twice as many miracles through Elisha (28 miracles) as took place through Elijah (14 miracles).
