For I, saith the LORD, will be to her a wall of {d} fire on every side, and will {e} be the glory in the midst of her.

(d) To defend my Church, to strike fear in the enemies, and to destroy them if they approach near.

(e) In me they will have their full felicity and glory.

Wesley's Notes

2:5 The glory - My presence and favour shall make her glorious.

Jamieson-Fausset-Brown Bible Commentary

5. I . wall of fire round-Compare Zec 2:4. Yet as a city needs some wall, I Jehovah will act as one of fire which none durst approach (Zec 9:8; Isa 26:1).

glory in the midst-not only a defense from foes outside, but a glory within (Isa 60:19; Re 21:23). The same combination of "glory and defense" is found in Isa 4:5, alluding to the pillar of cloud and fire which defended and enlightened Israel in the desert. Compare Elisha in Dothan (2Ki 6:17). As God is to be her "glory," so she shall be His "glory" (Isa 62:3).

Matthew Henry's Concise Commentary

2:1-5 The Son of David, even the Man Christ Jesus, whom the prophet sees with a measuring line in his hand, is the Master-Builder of his church. God notices the extent of his church, and will take care that whatever number of guests are brought to the wedding-supper, there shall be room. This vision means well to Jerusalem. The walls of a city, as they defend it, so they straiten its inhabitants; but Jerusalem shall be extended as freely as if it had no walls at all, yet shall be as safe as if it had the strongest walls. In the church of God there yet is room for other multitudes, more than man can number. None shall be refused who trust in Christ; and He never shuts out from heaven one true member of the church on earth. God will be a Wall of fire round them, which can neither be broken through nor undermined, nor can it be assailed without danger to those who attack. This vision was to have its full accomplishment in the gospel church, which is extended by admitting the Gentiles into it; and which has the Son of God for its Prince and Protector; especially in the glorious times yet to come.
