And Jesus returned0 in the power of the Spirit into Galilee In the Greek bwdfjui, in the power, strength, or force of the Spirit Under a strong impulse of the Spirit, Jesus returned to Galilee. For the Holy Ghost was moving Him, and powerfully impelling Him to put forth at this time that spiritual power which He had received from the beginning of His conception, but which He had hitherto shut up and hidden within Himself, and to begin in Galilee with immense ardour and zeal, His ministry of preaching, and confirm it by His admirable holiness of life and His stupendous miracles. Hence Theophylact renders it Momm, driven and urged on by the enthusiasm and Divine afflatus of the Holy Ghost
