▼ Heb “will serve you,” i.e., be available as sacrifices (see the next line). Another option is to understood these “rams” as symbolic of leaders who will be subject to the people of Zion. See v. 10.

▼ Heb “they will go up on acceptance [on] my altar.” Some have suggested that the preposition עַל (’al) is dittographic (note the preceding יַעֲלוּ [ya’alu]). Consequently, the form should be emended to לְרָצוֹן (l^eratson, “acceptably”; see BDB 953 s.v. רָצוֹן). However, the Qumran scroll 1QIsa^a has both לרצון followed by the preposition על, which would argue against deleted the preposition. As the above translation seeks to demonstrate, the preposition עַל (’al) indicates a norm (“in accordance with acceptance” or “acceptably”; IBHS 218 #11.2.13e, n. 111) and the “altar” functions as an objective accusative with a verb of motion (cf. Gen 49:4; Lev 2:2; Num 13:17; J. N. Oswalt, Isaiah [NICOT], 2:534, n. 14).
