Mark 9:12

“And he answered, and told them, etc..] Allowing that their observation was right, and that this was the sense of the Scribes, and that there was something of truth in it, when rightly understood: Elias verily cometh first, and restoreth all things: (see Gill on “<401711>Matthew 17:11”); and how it is written of the son of man, that he must suffer many things, and be set at nought.

“9:12 The teachers of the law were correct: Elijah must return before the consummation of God’s Kingdom, but Scripture also said that the Son of Man would suffer greatly (e.g., Ps 22; Isa 52:13–53:12).”

“restoreth: Mar 1:2-8; Isa 40:3-5; Mal 4:6; Mat 3:1-12, 11:2-18; Luk 1:16, Luk 1:17, Luk 1:76, Luk 3:2-6; John 1:6-36, Joh 3:27-30 he must: Psa. 22:1-31, 69:1-36; Isa 53:1-12; Dan 9:24-26; Zac 13:7 set: Psa 22:6, Psa 22:7, Psa 69:12, Psa 74:22; Isa 49:7, Isa 50:6, Isa 52:14, Isa 53:1-3; Zac 11:13; Luk 23:11, Luk 23:39; Phi 2:7, Phi 2:8 Mark 9:13”
