Zakharia 4:3

4:3 There are also two olive trees beside it, one on the right of the receptacle and the other on the left.” ¹ 

Zakharia 4:12

4:12 Before he could reply I asked again, “What are these two extensions ²  of the olive trees, which are emptying out the golden oil through the two golden pipes?”

[4:3]  ¹ sn The vision apparently describes two olive trees providing olive oil by pipes to a large basin atop the menorah. From this basin two pipes extend to each of the seven lamps of the menorah, for a total of fourteen pipes in all. See vv. 11-12.

[4:12]  ² tn The usual meaning of the Hebrew term שְׁבֹּלֶת (shÿbolet) is “ears” (as in ears of grain). Here it probably refers to the produce of the olive trees, i.e., olives. Many English versions render the term as “branches,” but cf. NAB “tufts.”
