Charles Ellicott Commentary Psalms 105:15

"[Saying], Touch not mine anointed ones, And do my prophets no harm." — Psalms 105:15 (ASV)

Anointed. —In the plural, “my anointed ones.” As referring to the patriarchs, the expression is not technical, since they were never, like priests, prophets, and kings in later times, actually anointed. But since these terms are sometimes applied to the covenant people as a whole (Psalms 89:51), its application to the founders of the race, especially those to whom the “promises came,” is entirely fitting.

Regarding the term “prophet,” the poet found it expressly conferred on Abraham in Genesis 20:7.
