“I do not receive praise (doxan - ‘praise, glory') from men.”
Jesus now contrasts Himself with the Judaisers. They constantly look for the praise of men (John 5:44). In contrast He does not seek such praise. Unlike these leaders of the Jews who seek praise from one another He does not seek praise as a man, or from men. He wants men's eyes to be turned on God so that they praise only God. For that is central to His purpose in coming, to turn men's eyes on God so that they might praise Him. Furthermore He Himself wants only praise from God. From His own point of view that is His only concern. Praise from men is unimportant to Him.
