Charles Ellicott Commentary Isaiah 1:14

"Your new moons and your appointed feasts my soul hateth; they are a trouble unto me; I am weary of bearing them." — Isaiah 1:14 (ASV)

Your new moons and your appointed feasts.—The latter word included the sabbaths (Leviticus 23:3). The words add nothing to what had been said before, but they come with all the emphasis of iteration.

My soul.—The words are in one sense anthropomorphic. With man the soul expresses the full intensity of life and consciousness, and so, in the language of the prophets, it does with God.
