Psalms 67:2

2That they may know thy way upon the earth. Here we have a clear prophecy of that extension of the grace of God by which the Gentiles were united into one body with the posterity of Abraham. The Psalmist prays for some conspicuous proof of favor to be shown his chosen people, which might attract the Gentiles to seek participation in the same blessed hope. (4) By the way of God is meant his covenant, which is the source or spring of salvation, and by which he discovered himself in the character of a Father to his ancient people, and afterwards more clearly under the Gospel, when the Spirit of adoption was shed abroad in greater abundance. (5) Accordingly, we find Christ himself saying,

“This is life eternal, that they might know thee the only true God,”
(John 17:3)
