הָעָ֗ם הַמַּכְעִיסִ֥ים אוֹתִ֛י עַל־פָּנַ֖י תָּמִ֑יד זֹֽבְחִים֙ בַּגַּנּ֔וֹת וּֽמְקַטְּרִ֖ים עַל־הַלְּבֵנִֽים׃
Rashi on Isaiah
those who sacrifice in gardens They erect idols in their gardens, and there they burn incense on the bricks.
Ibn Ezra on Isaiah
To my face. Like a servant that provokes his master while in his presence.
