tn The demonstrative “this” refers back to the hope just mentioned or forward to the statement in the second line concerning the promise’s power to revive. See the note on the word “me” at the end of the verse for further discussion.

tn The hope generated by the promise (see v. 49b) brings comfort because (note “for” at the beginning of the line) the promise revives the psalmist’s spirits. Another option is to take כִּי (ki) at the beginning of the second line in the sense of “that,” in which case “this” refers to the promise’s power to revive.
