continually - answering to “all the day” (Isa 65:2). God was continually inviting them, and they continually offending Him (Deu 32:21).
to my face - They made no attempt to hide their sin (Isa 3:9). Compare “before Me” (Exo 20:3).
in gardens - (See on Isa 1:29; Isa 66:17; Lev 17:5).
altars of brick - Hebrew, “bricks.” God had commanded His altars to be of unhewn stone (Exo 20:25). This was in order to separate them, even in external respects, from idolaters; also, as all chiseling was forbidden, they could not inscribe superstitious symbols on them as the heathen did. Bricks were more easily so inscribed than stone; hence their use for the cuneiform inscriptions at Babylon, and also for idolatrous altars. Some, not so well, have supposed that the “bricks” here mean the flat brick-paved roofs of houses on which they sacrificed to the sun, etc. (2Ki 23:12; Jer 19:13).
