ذِكْرُ رَحْمَتِ رَبِّكَ عَبْدَهُ زَكَرِيَّا (2)
(19:2) Here is an accounts *1 of the mercy your Lord showed to His servant Zachariah *2
*1) For comparison please see the story of Zachariah as given in vv. 3457 of Al-i-`Imran (III) and the E.N.'s there of.
*2) In order to understand the position held by Hadrat Zachariah, a descendant ' of Prophet Aaron, one should be acquainted with the system of priesthood among the children of Israel.
After the conquest of Palestine, the whole land was divided among the 12 tribes of the descendants of Prophet Jacob as inheritance, and the 13th tribe (the Levites) were entrusted with religious services and duties. Even among the Levites, the house that was separated "to sanctify the most holy things .... to burn incense before the Lord, to minister unto him, and to bless in his name for ever" was the house of Prophet Aaron. The other Levites were not allowed to enter the Temple? "Because their office was to wait on the sons of Aaron for the service of the house of the Lord, in the courts, and in the chambers, and in the purifying of all holy things, and the work of the service of the house of the God .... And to offer all burnt sacrifices unto the Lord in the Sabbaths, in the new moon, and on the set festivals." The descendants of Aaron were divided into 24 families, who came to serve the house of the Lord by turns. One of these families was of Abiah whose chief was Zachariah. Thus it was Zachariah's duty to go into the house on his family's turn and burn incense before the Lord. (For details, see I Chronicles, chapters 23, 24).
