Midrash su Salmi 122:1

This is what Scripture says. "To do what is right and just is more desired by the Lord than sacrifice." (Prov. 21:3) Scripture does not say, "as much as sacrifice", but "more than sacrifice." How so?Whereas sacrifices could only function inside the Temple, to do what is right and just is mandated inside and outside the Temple. Another opinion: whereas sacrifices could only atone for unintentional, accidental sins, acts of righteousness and justice atone even for intentional sins. Another opinion: whereas sacrifices are offered only by humanity, even God is obligated to practice justice and righteousness. Another opinion: whereas sacrifices are significant only in this world, righteousness and justice will remain a cornerstone in the Coming World. Rabbi Shmuel ben Nachmani said: When the Holy One of Blessing said to Natan (I Chronicles 17:3-5): "Go and tell David My servant: Thus saith the LORD: Thou shalt not build Me a house to dwell in for I have not dwelt in a house since the day that I brought up Israel, unto this day; but have [gone] from tent to tent, and from one tabernacle [to another]" If a person wanted to curse David, what would he do? He would say to David: It would be good if you built the House. You should know what David's answer was: (Ps. 122) 'I was glad when they said to me, let's go to the House of Hashem'.

"He shall set it up in the tent of meeting outside the curtain of the pact" (Leviticus 24:3). Rabbi Elazar said, "In the merit of, 'set up,' they were saved from 'It has been set up for a long time' (Isaiah 30:33)." Rabbi Chanin said, "In the merit of the perpetual light, you have merited to receive the face of the lamp of the King Messiah." What is the reason? "There I will make a horn sprout for David; I have prepared a lamp for My anointed one" (Psalms 132:17); and it states (Psalms 122:1), "I rejoiced when they said to me, 'We are going to the House of the Lord.'"
