The Lord (יהוה Yeve or Jehovah) said unto my Lord, אדניע Adni or Adonai, my prop, stay, master, support), Sit thou on my right hand - Take the place of the greatest eminence and authority. Till I make thine enemies thy footstool - till I subdue both Jews and Gentiles under thee, and cause them to acknowledge thee as their sovereign and Lord. This quotation is taken from Psalm 110:1; and, from it, these two points are clear:

1. That David wrote it by the inspiration of God; and

2. That it is a prophetic declaration of the Messiah.

The Lord. This passage is expressly referred to the Messiah by several of the Jews. Rabbi Joden says, 'In the world to come, the Holy Blessed God shall cause the king Messiah to sit at his right hand, as it is written, The Lord said to my Lord,' etc. So Rabbi Moses Hadarson; and Saadias Gaon says, 'This is Messiah our righteousness, as it is written, The Lord said to my Lord,' etc.

On the Same Words of the Gospel, Matt. xxii. 42
1. The question which was proposed to the Jews, Christians ought to solve. For the Lord Jesus Christ, who proposed it to the Jews, did not solve it Himself, to the Jews, I mean, He did not, but to us He hath solved it. I will put you in remembrance, Beloved, and ye will find that He hath solved it. But first consider the knot of the question. He asked the Jews what they "thought of Christ, whose Son He was to be;" for they too look for the Christ. They read of Him in the Prophets, they expected Him …

The Heavenly Banquet.
20th Sunday after Trinity. S. Matt. xxii. 4. "Behold, I have prepared my dinner; my oxen and my fatlings are killed, and all things are ready; come unto the marriage." INTRODUCTION.--The Kingdom of Heaven has two meanings in this parable. It means in the first place the Catholic Church. Into that the apostles and pastors of Christ invite men to enter, and many refuse. In the second place it means the Church Triumphant,--eternal blessedness, and into that the pastors of Christ's Church invite you …

Profession and Practice.
18th Sunday after Trinity. S. Matt. xxii. 42. "What think ye of Christ?" INTRODUCTION.--Many men are Christians neither in understanding nor in heart. Some are Christians in heart, and not in understanding. Some in understanding, and not in heart, and some are Christians in both. If I were to go into a Temple of the Hindoos, or into a Synagogue of the Jews, and were to ask, "What think ye of Christ?" the people there would shake their heads and deny that He is God, and reject His teaching. The …
