21 but taking his leave of them, and saying, "I must by all means keep this coming feast in Jerusalem, but I will return again to you if God wills," he set sail from Ephesus.
*Minor differences ignored. Grouped by changes, with first version listed as example.
Keep this feast - Probably the Passover is here referred to. Why he was so anxious to celebrate that feast at Jerusalem, the historian has not informed us. It is probable, however, that he wished to meet as many of his countrymen as possible, and to remove, if practicable, the prejudices which had everywhere been raised against him, Acts 21:20-21. Perhaps, also, he supposed that there would be many Christian converts present, whom he might meet also.
But I will return - This he did Acts 19:1, and remained there three years, Acts 20:31.
I must - keep this feast - Most likely the passover, at which he wished to attend for the purpose of seeing many of his friends, and having the most favorable opportunity to preach the Gospel to thousands who would attend at Jerusalem on that occasion. The whole of this clause, I must by all means keep this feast that cometh in Jerusalem, is wanting in ABE, six others; with the Coptic, Ethiopic, Armenian, and Vulgate. Griesbach leaves it in the text, with the mark of doubtfulness; and Professor White, in his Crisews, says, probabiliter delenda. Without this clause the verse will read thus: But he bade them farewell, saying, I will return again unto you, if God will. And this he did before the expiration of that same year, Acts 19:1, and spent three years with them, Acts 20:31, extending and establishing the Church at that place.
But bade them farewell, saying, I must by all means keep this feast that cometh in Jerusalem: but I will return again unto you, (m) if God will. And he sailed from Ephesus.
(m) So we should promise nothing without this clause, for we do not know what the following day will bring forth.
But bade them farewell, saying,.... As follows:
I must by all means keep this feast that cometh in Jerusalem; which perhaps was the passover, since that often went by the name of the feast: the why he must by all means keep it, was not because it was obligatory upon him; nor did he always observe it, as appears from his long stay at Corinth, and other places; and besides, as a Christian, he had nothing to do with it; but either because of his vow, Acts 18:18 or because he knew he should have an opportunity of preaching the Gospel to great numbers; the Vulgate Latin and Ethiopic versions omit this clause:
but I will return again unto you, if God will; he promises to return to them, but not peremptorily as knowing that he was altogether subject to the will of God, who disposes and orders all things according to his sovereign pleasure; see James 4:15 and he sailed from Ephesus; which was near the Aegean sea: such was the situation of Ephesus, according to Apollonius (f); who says, that it stood out to the sea, which encompassed the land on which it was built; so Pausanias (g) relates, that Lysimachus passing into Asia by shipping, took the kingdom of Antigonus from him, and built the city the Ephesians now inhabit near the sea; so Josephus (h) reports of Herod and Agrippa, that travelling by land to Phrygia Major, they came to Ephesus, and again, "they sailed from Ephesus" to Samos.

I must . . . keep this feast--probably Pentecost, presenting a noble opportunity of preaching the Gospel.
but I will return--the fulfilment of which promise is recorded in Acts 19:1.
I must by all means keep the feast at Jerusalem - This was not from any apprehension that he was obliged in conscience to keep the Jewish feasts; but to take the opportunity of meeting a great number of his countrymen to whom he might preach Christ, or whom he might farther instruct, or free from the prejudices they had imbibed against him. But I will return to you - So he did, Acts 19:1.
