Compass sea and land - A proverbial expression, similar to ours, You leave no stone unturned; intimating that they did all in their power to gain converts, not to God, but to their sect. These we may suppose were principally sought for among the Gentiles, for the bulk of the Jewish nation was already on the side of the Pharisees.

Proselyte - Προσηλυτος, a stranger, or foreigner; one who is come from his own people and country, to sojourn with another. See the different kinds of proselytes explained in the note on Exodus 12:43 (note).

The child of hell - A Hebraism for an excessively wicked person, such as might claim hell for his mother, and the devil for his father.

Twofold - the child of - The Greek word διπλοτερον, which has generally been translated twofold, Kypke has demonstrated to mean more deceitful. Απλοῦς is used by the best Greek writers for simple, sincere, απλότης for simplicity, sincerity; so διπλοῦς, deceitful, dissembling, and διπλόη, hypocrisy, fraudulence, and διπλοτερον, more fraudulent, more deceitful, more hypocritical. See also Suidas in Διπλοη.

Dr. Lightfoot, and others, observe, that the proselytes were considered by the Jewish nation as the scabs of the Church, and hindered the coming of the Messiah; and Justin Martyr observes, that "the proselytes did not only disbelieve Christ's doctrine, but were abundantly more blasphemous against him than the Jews themselves, endeavoring to torment and cut off the Christians wherever they could; they being in this the instruments of the scribes and Pharisees."

First Attempts on Jerusalem.
Jesus, almost every year, went to Jerusalem for the feast of the passover. The details of these journeys are little known, for the synoptics do not speak of them,[1] and the notes of the fourth Gospel are very confused on this point.[2] It was, it appears, in the year 31, and certainly after the death of John, that the most important of the visits of Jesus to Jerusalem took place. Many of the disciples followed him. Although Jesus attached from that time little value to the pilgrimage, he conformed …

On Attending the Church Service
"The sin of the young men was very great." 1 Sam. 2:17. 1. The corruption, not only of the heathen world, but likewise of them that were called Christians, has been matter of sorrow and lamentation to pious men, almost from the time of the apostles. And hence, as early as the second century, within a hundred years of St. John's removal from the earth, men who were afraid of being partakers of other men's sins, thought it their duty to separate from them. Hence, in every age many have retired from …

Machinations of the Enemies of Jesus.
Jesus passed the autumn and a part of the winter at Jerusalem. This season is there rather cold. The portico of Solomon, with its covered aisles, was the place where he habitually walked.[1] This portico consisted of two galleries, formed by three rows of columns, and covered by a ceiling of carved wood.[2] It commanded the valley of Kedron, which was doubtless less covered with debris than it is at the present time. The depth of the ravine could not be measured, from the height of the portico; and …
