Augustine of Hippo
He who sang these truths in the Spirit foresaw what was to come and, filled with joy, lifted his voice in praise, declaring, Blessed be the Lord God, blessed be the Lord God from day to day (Psalm 68:19). In certain translations, the phrase appears as 'day daily,' reflecting the Greek phrasing ἡ μ-ραν καθ' ἡμ-ραν, which could more accurately be rendered as 'day by day.' This phrase signifies the same idea that has been communicated, that He acts every day. For He continuously performs this until the end, leading captivity captive and receiving gifts from humanity.
