Days of unleavened bread - The seven days of the passover, in which they ate unleavened bread. See the account of this festival in the notes on Exodus 12:1-51 (note). It is evident, from the manner in which St. Luke writes here, that he had not been with St. Paul since the time he accompanied him to Philippi, Acts 16:10-12; but he now embarks at Philippi with the apostle, and accompanies him to Troas, and continues with him through the rest of his journey.

To Troas in five days - So long they were making this voyage from Philippi, being obliged to keep always by the coast, and in sight of the land; for the magnetic needle was not yet known. See the situation of these places upon the map.

"None of these things move me" (Acts xx. 24). The best evidence of God's presence is the devil's growl. So wrote good Mr. Spurgeon once in "The Sword and the Trowel," and that little sentence has helped many a tried and tired child Of God to stand fast and even rejoice under the fiercest attacks of the foe. We read in the book of Samuel that the moment that David was crowned at Hebron, "All the Philistines came up to seek David." And the moment we get anything from the Lord worth contending for, …

The Minister's Farewell
WHEN Paul was parting from his Ephesian friends, who had come to bid him farewell at Miletus, he did not request of them a commendation of his ability; he did not request of them a recommendation for his fervid eloquence, his profound learning, his comprehensive thought, or his penetrating judgment. He knew right well that he might have credit for all these, and yet be found a castaway at last. He required a witness which would be valid in the court of heaven, and of value in a dying hour. His one …
