A.T. Robertson Commentary Luke 22:53

"When I was daily with you in the temple, ye stretched not forth your hands against me: but this is your hour, and the power of darkness." — Luke 22:53 (ASV)

But this is your hour (αλλ' αυτη εστιν υμων η ωρα). So Jesus surrenders. The moral value of his atoning sacrifice on the Cross consists in the voluntariness of his death. He makes it clear that they have taken undue advantage of him in this hour of secret prayer and had failed to seize him in public in the temple. But "the power of darkness" (η εξουσια του σκοτους), had its turn. A better day will come. The might, authority of darkness.
