The sparrow hath found an house, i.e. a habitation, to wit, a nest, as it here followeth. Even thine altar; or, nigh (as this Hebrew particle eth is elsewhere used, and as it is rendered by the Septuagint and the Chaldee, Judges 4:11) thine altar, Heb. altars, that of burnt-offerings, and the other of incense; at or near which these birds might well and truly be said to have their nests, because they were either in some part of the tabernacle or temple in which the altars were, or in some buildings belonging, or near at least, to it.
