“And Melchizedek king of Salem brought forth bread and wine; he was priest of G-d the Most High.” – Genesis 14:18, JPS 1917 Tanach
A tenth of all that Abraham retrieved from the five kings was given to Melchizedek; the remainder was considered properly tithed from the perspective of a later Torah injunction; yet, Abraham kept none of this, for his reward has to do with heaven and earth. Therefore, what has any man to offer Abraham? The King of Sodom’s riches would have been devoid of any spiritual blessing, since they would not have been bestowed upon Abraham by G-d; but, rather by man.
While it is true that blessings can be given to someone through men, according to G-d’s design, this would not have been the case, in regard to the loot that was recovered by Abraham, when he rescued his nephew Lot, who was captured by the five kings. Why? Because Abraham was righteous, and “disdained profit gained through oppression” (Akeidas Yitzchak; sefaria.org). That is to say that he forsook the wealth that was rightly his according to custom in order to maintain his integrity.
Every now and then, we may find ourselves in a similar position, not necessarily having to do with possessions; rather, as pertaining to a challenge designed to test the integrity of our convictions. Our belief and practice, as well as the strength of our convictions must be tested, so that we are able to permit these to take root in actuality. Otherwise, how would we know whether we have what it takes to act upon our convictions?
Although we have potential, whether from inborn traits or learned moral qualities that we have acquired along the way, some of these may only be in a potential resting state, until activated by the challenges in our lives. Everything in our lives that is presented to us as a challenge, obstacle, or hurdle, has a reason, concomitant with our purpose in life. It is our integrity that is born out of the way we meet these existential realities; and, if we handle them well, then we may increase in moral strength and character.
