According to the Mishnah (Jewish book), certain psalms were recited on certain days of the week in the Temple and would have been in Jesus’ time:
The following are the Psalms that were chanted in the Temple. On the first day, they used to say, "The earth is the Lord's and the fullness thereof, the world and they that dwell therein" (Psalm 24). On the second day, they used to say, "Great is the Lord and highly to be praised, in the city of our God, His Holy mountain" (Psalm 48). On the third day, they used to say, "God standeth in the congregation of God, in the midst of the judges He judgeth" (Psalm 82). On the fourth day, they used to say, "O Lord, Thou God to whom vengeance belongeth, shine forth" (Psalm 94). On the fifth day, they used to say, "Sing aloud unto God our strength, shout aloud to the God of Jacob" (Psalm 81). On the sixth day, they used to say, "A Psalm. A song for the sabbath day (Psalm 92). A Psalm, a song for the time to come, for the day that will be all sabbath and rest for everlasting life."
