This certainly applies to Paul's commentary on Melchizedek which is recorded in Hebrews; he himself admitted he was going deep, speaking of things which could only be grasped by very mature believers (Heb.5:10,11,14).
Hakika huu unatumika juu ya ufafanuzi wa Paulo kwa Melkizedeki ulioandikwa kwa Waebrania; yeye mwenyewe alikiri aliingia ndani sana ya maandiko, akinena mambo ambayo yaweza kueleweka tu na waamini waliokomaa sana kwenye maandiko (Ebra. 5: 10, 11, 14).
