Charles Ellicott Commentary Psalms 28:9

"Save thy people, and bless thine inheritance: Be their shepherd also, and bear them up for ever." — Psalms 28:9 (ASV)

Feed ... lift them up. —These words suggest comparison with Isaiah 40:11; Isaiah 63:9. The incorporation of this petition in the Te Deum is one of those interesting facts that link the Christian worship with the Jewish.
