Adam Clarke on Isaiah 48:1

Are come forth out of the waters of Judah "Ye that flow from the fountain of Judah" - ממי mimmey, "from the waters." Perhaps ממעי mimmeey, "from the bowels," So many others have conjectured, or מני יהודה meni yehudah, or מיהודה meyhudah, "from Judah." - Secker. But see Michaelis in Praelect, not. 22. And we have עין יעקב eyn yaakob, "the fountain of Jacob," Deu 33:28, and ממקור ישראל mimmekor yishrael, "from the fountain of Israel," Psa 68:27. Twenty-seven MSS. of Kennicott's, six of De Rossi's and two of my own, with six editions, have מימי meymey, "from the days;" which makes no good sense.
