[23:39] 1 sn A quotation from Ps 118:26.
[21:9] 2 tn Grk “were shouting, saying.” The participle λέγοντας (legontas) is redundant here in contemporary English and has not been translated.
[21:9] 3 tn The expression ῾Ωσαννά (Jwsanna, literally in Hebrew, “O Lord, save”) in the quotation from Ps 118:25-26 was probably by this time a familiar liturgical expression of praise, on the order of “Hail to the king,” although both the underlying Aramaic and Hebrew expressions meant “O Lord, save us.” In words familiar to every Jew, the author is indicating that at this point every messianic expectation is now at the point of realization. It is clear from the words of the psalm shouted by the crowd that Jesus is being proclaimed as messianic king. See E. Lohse, TDNT 9:682-84.
