"To the conductor, a psalm of David. The heavens declare the glory of God, as it is said (Proverbs 16:4) 'The Lord has made everything for its purpose.' [This is] according to what is stated (Psalm 107:22) 'Let them offer sacrifices of thanksgiving and tell of his deeds with songs of joy.' Another [reason] is to testify to Him, as it is said (Exodus 20:7) 'You shall not bear false witness against your neighbor.'
And it is written (Psalm 122:8) 'For the sake of my brothers and companions.' Rabbi Avihu said there are two things that the nations of the world do not deny the Holy One, blessed be He, for having created the world in six days, and for reviving the dead. How does a person go up [to Jerusalem] and make mention of [the Temple] all the days of the week and then on the Sabbath he goes up [to Jerusalem] and does not make mention of it?
And even an animal does not go up on the Sabbath, because it is not alive for the future [world]." "Woe to all the works of the Lord, to all his delights in creation!"
