Psalms 118:26

Blessed [be] he that cometh in the name of the Lord
These words were used by the multitude that followed Christ, as he went into Jerusalem, in order to eat his last passover, and suffer and die for his people, and are applied to him; as also by his disciples, who expressed them thus, "Blessed be the King that cometh" ( Luke 19:38 ) ; the King Messiah, who came from heaven to earth, from his Father into this world, to save the chief of sinners; who now came to Jerusalem on that errand, and into the temple, as the proprietor of it; where he showed his power, and exercised his authority: he came not in his own name, but in his Father's name; and not to do his own will, but his; nor did he seek his own glory, but his Father's: he came as his servant to do his work; he came with a commission from him, by his order, and to obey his commands, which he did; he came with his full consent and will, and, as man and Mediator, was helped and assisted by him; and as such he is pronounced blessed: all blessing, happiness, and honour, are wished for him, and ascribed unto him, as his just due; being Lord and King, Saviour and Redeemer, of his people;

we have blessed you out of the house of the Lord;
these are the words of the priests, one part of whose office it was to bless the people, ( Numbers 6:23-27 ) ; but these were not the chief priests of the Jews in Christ's time; for they were displeased with the multitude, and with the children in the temple, for crying "hosanna" to the son of David, and wishing well to him, ( Matthew 21:15 Matthew 21:16 ) . But the disciples of Christ, or ministers of the Gospel, who blessed the people that blessed their Lord and Master; or wished well to them, and prayed for them that wished well to him. The sense is, either we who are of the house of the Lord bless you; we who stand there, and serve him, are rulers of the household of God, and stewards of the mysteries of grace: or we bless you, and pray for your welfare, who are of the household of faith; who are fellow citizens with the saints, and of the household of God: or we bless you with provisions out of the house of God; with the goodness and fatness of his house, the word and ordinances, by administering them to you: or we pray that the Lord would bless you out of Zion, or out of the highest heavens, where he is; even with all spiritual blessings, in heavenly places in Christ Jesus; see ( Psalms 134:1-3 ) . The Targum of this verse ( Psalms 118:25 ) , is,

``We beseech thee, O Lord, "save" now, said the builders; We beseech thee, O Lord, send now prosperity, said Jesse and his wife. Blessed be he that cometh in the name of the Lord, said the builders; Let us bless you out of the house of the sanctuary of the Lord, said David.''
