After five days - These days are to be reckoned from the time in which Paul was apprehended at Jerusalem, and twelve days after he had arrived in that city; see Acts 24:11. Calmet reckons the days thus: - St. Luke says that Paul was apprehended at Jerusalem when the seven days of his vow were nearly ended, Acts 21:27; that is, at the end of the fifth day after his arrival. The next day, which was the sixth, he was presented before the Sanhedrin. The night following, he was taken to Antipatris. The next day, the seventh, he arrived at Caesarea. Five days afterwards, that is, the twelfth day after his arrival at Jerusalem, the high priest and the elders, with Tertullus, came down to accuse him before Felix. - But see the note on Acts 23:32.

A certain orator named Tertullus - This was probably a Roman proselyte to Judaism; yet he speaks every where as a Jew. Roman orators, advocates; etc., were found in different provinces of the Roman empire; and they, in general, spoke both the Greek and Latin languages; and, being well acquainted with the Roman laws and customs, were no doubt very useful. Luitprandus supposed that this Tertullus was the same with him who was colleague with Pliny the younger, in the consulate, in the year of Rome, 852; who is mentioned by Pliny, Epist. v. 15. Of this there is no satisfactory proof.

A Loyal Tribute
[Footnote: Preached on the occasion of the Jubilee of Queen Victoria.] '...Seeing that by thee we enjoy great quietness, and that very worthy deeds are done unto this nation by thy providence, 3. We accept it always ... with all thankfulness.'--ACTS xxiv. 2-3. These words were addressed by a professional flatterer to one of the worst of the many bad Roman governors of Syria. The speaker knew that he was lying, the listeners knew that the eulogium was undeserved; and among all the crowd of bystanders …

The Witness of Our Own Spirit
"This is our rejoicing, the testimony of out conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world." 2 Cor. 1:12 1. Such is the voice of every true believer in Christ, so long as he abides in faith and love. "He that followeth me," saith our Lord, "walketh not in darkness:" And while he hath the light, he rejoiceth therein. As he hath "received the Lord Jesus Christ," so he walketh in him; and while he walketh …

The Parables Exemplified in the Early History of the Church.
"To Him shall prayer unceasing And daily vows ascend; His Kingdom still increasing, A Kingdom without end." We have seen that our Lord described in His Parables the general character and nature of "The Kingdom of Heaven." Consequently, if the Church established by the Apostles under the guidance of the Holy Ghost is "The Kingdom of Heaven," it will necessarily be found to agree with the description thus given. Let us therefore now consider how far the history of the Church, in the Acts of the Apostles …
