manifestly optatives. Mountains and hills describe synecdochically the whole land of which they are the high points visible afar off. נשׂא is used in the sense of נשׂא פּרי Eze 17:8 : may שׁלום be the fruit which ripens upon every mountain and hill; universal prosperity satisfied and contented within itself. The predicate for Psa 72:3 is to be taken from Psa 72:3, just as, on the other hand, בּצדקה, “in or by righteousness,” the fruit of which is indeed peace (Isa 32:17), belongs also to Psa 72:3; so that consequently both members supplement one another. The wish of the poet is this: By righteousness, may there in due season be such peaceful fruit adorning all the heights of the land. Psa 72:3, however, always makes one feel as though a verb were wanting, like תּפרחנה suggested by Böttcher. In Psa 72:4 the wishes are continued in plain unfigurative language. הושׁיע in the signification to save, to obtain salvation for, has, as is frequently the case, a dative of the object. בּני־אביון are those who are born to poverty, just like בּן־מלך, one who is born a king. Those who are born to poverty are more or less regarded, by an unrighteous government, as having no rights.
Verses 5-8
The invocation of Psa 72:1 is continued in the form of a wish: may they fear Thee, Elohim, עם־שׁמשׁ, with the sun, i.e., during its whole duration (עם in the sense of contemporary existence, as in Dan. 3:33). לפני־ירח, in the moonlight (cf. Job 8:16, לפני־שׁמשׁ, in the sunshine), i.e., so long as the moon shines. דּור דּורים (accusative of the duration of time, cf. Psa 102:25), into the uttermost generation which outlasts the other generations (like שׁמי השּׁמים of the furthest heavens which surround the other heavens). The first two periphrastic expressions for unlimited time recur in Psa 89:37., a Psalm composed after the time of Solomon; cf. the unfigurative expression in Solomon's prayer at the dedication of the Temple in 1Ki 8:40. The continuance of the kingship, from the operation of which such continuance of the fear of God is expected, is not asserted until Psa 72:17. It is capricious to refer the language of address in Psa 72:5 to the king (as Hupfeld and Hitzig do), who is not directly addressed either in Psa 72:4, or in Psa 72:6, or anywhere in the Psalm. With respect to God the desire is expressed that the righteous and benign rule of the king may result in the extension of the fear of God
