6 And they were both tzaddikim before Hashem, walking a derech tamim in all the mitzvot and chukkim of the Torah of Adoneinu. [BERESHIS 6:9; DEVARIM 5:33; MELACHIM ALEF 9:4]
7 But they had no ben, because Elisheva was barren, and they were both advanced in their yamim.
8 And it came to pass in the performance of his avodas kodesh sherut as a kohen before Hashem in the appointed order of his division, [DIVREY HAYAMIM ALEF 24:19; DIVREY HAYAMIM BAIS 8:14]
9 According to the minhag (custom) of the kehunah, Zecharyah was chosen by lot to enter the Beis Hamikdash and to offer ketoret (incense). [SHEMOT 30:7,8; DIVREY HAYAMIM ALEF 23:13; DIVREY HAYAMIM BAIS 29:11; TEHILLIM 141:2]
10 And when the hour of the offering of the ketoret came, all the multitude were davening outside. [VAYIKRA 16:17]
11 And there appeared to Zecharyah a malach Hashem, standing on the right side of the Mizbeach of ketoret. [SHEMOT 30:1-10]
12 And, seeing the malach, Zecharyah was terrified, and pachad (fear) fell on him. [SHOFETIM 6:22,23; 13:22]
