Midrash sa 1 Cronica 29:10: Midrash Tanchuma Buber & Bereshit Rabbah

(Exod. 21:1:) AND THESE ARE THE ORDINANCES (mishpatim)…. This text is related (to Ps. 99:4): AND A MIGHTY KING LOVES JUSTICE (mishpat).¹Tanh., Exod. 6:1; M. Pss. 99:2; Exod. R. 30:1. All strength, might, and glory belong to the Holy One. David said (in I Chron. 29:10): TO YOU, O LORD, BELONG THE GREATNESS AND THE MIGHT…. <Such> strength belongs to the Supreme King of Kings, the Holy One. You find that whoever is in a position of power does not accomplish his ends with justice (mishpat) but <instead> subverts justice. The Holy One, however, is in a position of power and <still> loves justice (mishpat). (Ps. 99:4, cont.:) YOU HAVE ESTABLISHED UPRIGHTNESS. R. Alexandri said: Two donkey drivers who hated each other were going along the road.²M.Pss.99:3. When the donkey belonging to one of them lay down, his companion saw it and passed by. After he had passed by, he thought: It is written in the Torah (in Exod. 23:5): WHEN YOU SEE THE DONKEY OF ONE WHO HATES YOU <LYING DOWN UNDER ITS BURDEN>…, [YOU MUST SURELY ASSIST HIM.]³Cf. ARN, A 23; Matthew 5:43–48; //Luke 6:27–28, 32–36; Romans 12:20. He immediately returned and shared the load with him. He began to consider <the matter > in his heart. He thought: So-and-so actually loves me,⁴The Buber text reads, “him.” and I did not know it! They entered an inn,⁵Gk.: pandokeion. to eat and drink. Who caused them to make peace? <It happened> because this person considered the Torah. (Ps. 99:4, cont.:) YOU HAVE ESTABLISHED UPRIGHTNESS…. What is this? This is justice (mishpat).

Rav Huna said in the name of Rav Idi: It is written: “The people rejoiced in their donation, because they donated to the Lord wholeheartedly, and King David too rejoiced with great joy” (I Chronicles 29:9) – because they were engaged in the mitzva of donation and they were successful, that is why they rejoiced. Therefore, what does it say? “David blessed the Lord before the eyes of the entire congregation [and David said: Blessed is the Lord, God of Israel our father]…” (I Chronicles 29:10). It does not say here: “God of Abraham, Isaac, and Israel,” but rather, “God of Israel our father” – he ascribed the vow to the one who began with it first. Rabbi Yehuda said: This place is also not lacking.¹There is no need to go to Chronicles for proof, as there is proof elsewhere in the Bible. “Israel took a vow [vayidru]²Plural.” is not written here, but rather, “Israel took a vow [vayidar]³Singular.” (Numbers 21:2) – Israel the elder.
