Patrick/Lowth/Whitby/Lowman Commentary

They forsook the Lord, and served Baal and Ashtaroth. Especially they worshipped the sun, and the moon, or Venus; which some understand by Astarte. In the next chapter, it is said they worshipped Baalim and the groves, Jg 3:7. For in those groves several goddesses, under the name of Ashtaroth, were worshipped, as Mr. Selden conjectures in his Syntag. 2. De Diis Syris, cap. 2, where he shows there were many Astartes among the heathen, as there were Baals: and therefore the Scripture speaks of them in the plural number because of the multitude of images representing Juno, or Venus, or Diana, which had the name of Ashtaroth, signifying (as some think) as much as Beatas, blessed.

John Wesley’s Notes on the Old and the New Testaments

Verse 13. Baal and Ashtaroth-That is, the sun and moon, whom many Heathens worshipped, tho’ under divers names; and so they ran into that error which God had so expressly warned them against, De 4:19. Baalim signifies lords, and Ashtaroth, blessed ones, he-gods and she-gods. When they forsook Jehovah, they had gods many and lords many, as a luxuriant fancy pleased to multiply them.
