Revelation 1:15

“And his feet like unto fine brass, as if they burned in a furnace, etc.] By which is meant, not his human nature in a suffering state; or his people, the meaner and lower parts of his mystical body, in a like state; or his apostles and ministers, who are supporters of his church, and run to and fro with spiritual knowledge, for which, though they suffer much, are permanent and glorious; but either the power of Christ in bearing up and supporting his people, in the care and government and defence of them; or his ways, works, and walks in his churches, and all his providential administrations towards them, which are holy, just, and righteous, and will be manifest; or his wrath and vengeance in…”

“fine brass--Greek, "chalcolibanus," derived by some from two Greek words, "brass" and "frankincense"; derived by BOCHART from Greek, "chalcos," "brass," and Hebrew, "libbeen," "to whiten"; hence, "brass," which in the furnace has reached a white heat.

Others regard it as from χαλκός chalkos, brass, and λιπαρόν liparon, clear. The metal referred to was undoubtedly a species of brass distinguished for its clearness…”

“And his feet like fine brass - Denoting his stability and strength. As if they burned in a furnace - As if having been melted and refined, they were still red hot. And his voice - To the comfort of his friends, and the terror of his enemies. As the voice of many waters - Roaring aloud, and bearing down all before them. Revelation 1:16”

“1:15 Refined or hardened bronze in the feet implies stability, firmness, and security (cp. Dan 10:6). • The thundering voice suggests God’s power—when he speaks, he will be heard (cp. Ezek 43:2).”

“his feet: Rev 2:18; Eze 1:7, Eze 40:3; Dan 10:6 his voice: Rev 14:2, Rev 19:6; Psa 93:4; Isa 17:13; Eze 43:2 Revelation 1:16”
