For my brethren and companions' sakes - Because they dwell there; or, because they go up there to worship; or, because they love thee, and find their happiness in thee; or, because they are unconverted, and all my hope of their salvation is to be derived from thee - from the church, from the influence of religion.

I will now say, Peace be within thee - I will pray for thy peace, for thy prosperity, for the blessing of God upon thee - because their good, their comfort, their hope of salvation, depends on thee - on the influence which shall go out from thee. So the Christian prays that the church may prosper - that the divine blessing may rest upon it - that there may be in it harmony, peace, love, and zeal - that a blessing may attend the preaching of the gospel - not only because he loves it, and seeks his own comfort and edification in it, but that his friends and kindred - his wife, his parents, his children, his neighbors - those whom he loves, and whose salvation he desires, may be saved. This expresses the true feelings of piety all over the world; this is one of the grounds of the strong love which the friends of God have for the church - because they hope and desire that through the church those most dear to their hearts will find salvation.

For any brethren and companions' sakes - Because this city is the abode of my kinsfolk and countrymen, I will wish it prosperity. I will promote its peace and tranquillity by all means in my power. I will affectionately say, May peace be within thee!

For my brethren and companions' sakes,.... Who were regenerated by the spirit of God; adopted into his family, and children of the same father; stood in the same relation to Christ the firstborn, and members of the same church; and so brethren: partners in the same blessings and promises of the covenant; partakers of the same grace; joined together in religious worship; shared in the same joys and griefs; travellers together to the same heavenly country, and entitled to the same glory and happiness. So David, though a king, reckoned his meanest subjects as such, who were spiritual men; and for their sakes, through the goodwill, love, and affection he bore to them, he would set praying souls an example, and by it enforce his own exhortation, as follows:

I will now say, peace be within thee; now and always put up this petition, and not put it off to longer time; that peace and prosperity may always attend the church of God, as well as the city of Jerusalem, literally considered, and the inhabitants of it.

For my {g} brethren and companions' sakes, I will now say, Peace be within thee.

(g) Not only for my own sake but for all the faithful.

8, 9. In the welfare of the city, as its civil, and especially the religious relations, was involved that of Israel.

now-as in Ps 115:2.

122:6-9 Those who can do nothing else for the peace of Jerusalem, may pray for it. Let us consider all who seek the glory of the Redeemer, as our brethren and fellow-travellers, without regarding differences which do not affect our eternal welfare. Blessed Spirit of peace and love, who didst dwell in the soul of the holy Jesus, descend into his church, and fill those who compose it with his heavenly tempers; cause bitter contentions to cease, and make us to be of one mind. Love of the brethren and love to God, ought to stir us up to seek to be like the Lord Jesus in fervent prayer and unwearied labour, for the salvation of men, and the Divine glory.
