Jamieson, Fausset and Brown on Ezekiel 34:26

26. them and the places round about my hill--The Jews, and Zion, God's hill (Psa 2:6), are to be sources of blessing, not merely to themselves, but to the surrounding heathen (Is 19:24; 56:6, 7; 60:3; Mi 5:7; Zec 8:13). The literal fulfilment is, however, the primary one, though the spiritual also is designed. In correspondence with the settled reign of righteousness internally, all is to be prosperity externally, fertilizing showers (according to the promise of the ancient covenant, Le 26:4; Psa 68:9; Mal 3:10), and productive trees and lands (Eze 34:27). Thus shall they realize the image of Eze 34:14; namely, a flock richly pastured by God Himself.
