Isaiah 15:2

“He is gone up to Bajith, &c.] That is, Moab; the king or people of Moab, particularly the inhabitants of the above cities. Bajith signifies house; and here a house of idolatry, as Kimchi interprets it; it was an idol’s temple, very likely the temple of their god Chemosh, the same which is called Bethbaalmeon, (<061317>Joshua 13:17) “the house of Baal’s habitation”, and is mentioned with Dibon and Bamoth, as here; hither the Moabites went in their distress, to lament their case, ask advice, make supplication, and offer sacrifice: and to Dibon, the high places, to weep; Dibon was another city of Moab, (<042130>Numbers 21:30) where probably were high places for idolatrous worship, and from…”

“He is gone up - That is, the inhabitants of Moab in consternation have fled from their ruined cities, and have gone up to other places to weep. To Bajith, and to Dibon - Lowth supposes that these two words should be joined together, and that one place is denoted. The Chaldee renders it, ‘Ascend into the houses of Dibon.’ Kimchi supposes that the word (בית bayith) denotes a temple. It usually means “house,” and hence, may mean a temple of the gods; that is, the principal “house” in the land. This interpretation is adopted by Gesenius and Noyes. Vitringa supposes it to mean Beth-Meon Jeremiah 48:24, or Beth-Baal-Meon Joshua 13:17, north of the Arnon, now “Macin.” I have adopted the translation…”

“Bajith - Which signifies an house. It is supposed to be some eminent house or temple of their idols. Dibon - Another city of Moab. To weep - To offer their supplications with tears to their idols for help. Medeba - Two considerable cities, anciently belonging to the Moabites. Beard - The hair of their heads and beards was shaved, as was usual in great mournings. Isaiah 15:3”

“15:2 In the ancient Near East, actions such as shaving or cutting off their beards revealed deep sorrow (see Jer 48:37).”

“is gone: Isa 16:12; Jos 13:17; Jer 48:18, Jer 48:22, Jer 48:23 Moab: Isa 15:3, Isa 14:31, Isa 16:7; Jer 48:31, Jer 48:39 Nebo: Num 32:3, Num 32:38; Deu 34:1; Jer 48:1 Medeba: Num 21:30; Jos 13:16 all: Isa 3:24, Isa 22:12; Lev 19:27, Lev 19:28, Lev 21:5; Deu 14:1; Job 1:20; Jer 7:29, Jer 47:5; Jer 48:1, Jer 48:37, Jer 48:38; Eze 7:18 Isaiah 15:3”

“But just as horror, when once it begins to reflect, is dissolved in tears, the thunder-claps in Isa 15:1 are followed by universal weeping and lamentation. "They go up to the temple-house and Dibon, up to the heights to weep: upon Nebo and upon Medebah of Moab there is weeping: on all heads baldness, every beard is mutilated. In the markets of Moab they gird themselves with sackcloth; on the roofs of the land, and in its streets, everything wails, melting into tears. Heshbon cries, and 'Elle; even to Jahaz they hear their howling; even the armed men of Moab break out into mourning thereat; its soul trembles within it." The people (the subject to עלה) ascend the mountain with the temple of…”
