Isa_30:17 (a) Here we have a beautiful picture of the testimony of GOD's people. This testimony is elevated high and shines plainly so that the light from it illuminates far and wide in this world. Every church should be a beacon, and so should every saved individual.

Beacon
(תֹּרֶן, to'ren), Isa_30:17, in the margin in that place, and in the text in chap. 23:23, and Eze_27:5, rendered mast. It probably signifies a pole used as a standard or ensign (נֵס, nes), which was set up on the tops of mountains as a signal for the assembling of the people, sometimes on the invasion of an enemy, and sometimes after a defeat (Isa_5:26; Isa_11:12; Isa_18:3; Isa_62:10).
