Psalms 128:6
Ver. 6. Yea, thou shall see thy children's children,.... A numerous race of descendants from him, which are the crown and glory of old men, Pr 17:6; this is also true of Christ's spiritual children by his church in successive ages, Isa 59:21;
[and] peace upon Israel: all kind of prosperity, temporal and spiritual; peace, and abundance of it; as will be in the latter day, in the spiritual reign of Christ, Ps 72:8. It may be considered as a wish or prayer, with which the psalm is concluded; let "peace be upon Israel" {a}, as in Ps 125:5; see Ga 6:16.
{a} larvy le Mwlv "pax sit super Israele", Cocceius; so Gejerus.
