Ps 113:2

“"For Your loving mercy, and for Your truth's sake" [Psalm 115:2]. Observe how often these two qualities, loving mercy and truth, are joined together in the holy Scriptures. For in His loving mercy He called sinners, and in His truth He judges those who when called refused to come. "That the heathen may not say, Where is now their God?" For at the last, His loving mercy and truth will shine forth, when "the sign of the Son of man shall appear in heaven, and then shall all tribes of the earth cry woe;" [Matthew 24:30] nor shall they then say, "Where is their God?" when He is no longer preached unto them to be believed in, but displayed before them to be trembled at.”

“Judah became His holy nation He took Judah as the lot of His portion and His sanctity, and even they sanctified His name when they descended into the sea, as the matter that is stated (above 68: 28): “the princes of Judah pelt them with stones.” Similarly, this verse is explained in the Aggadah (Mid. Ps. 114:8): Judah became His holy people, for Nahshon sprang into the sea and said, “I shall descend first,” and that is what [the Psalmist] says: Judah became His holy people.”
