Zech 4:12

12 I asked him the second time, “What are these two olive-branches, which are beside the two golden spouts, that pour the golden oil out of themselves?”

what are these two olive trees? – answered in Rev 11:4 as the two witnesses. They are the “two anointed ones who stand beside the Lord of the whole earth” (Zech 4:14) and oppose the desolator.
