Isaiah 52:6

The contempt thus brought on His name is the crowning motive of Jehovah's interposition, another point of affinity with Ezekiel (see Ezekiel 36:21).

my people shall know my name i.e. shall know by experience what My name imports; comp. "shall know that I am Jehovah," in Ezekiel (Ezekiel 20:42; Ezekiel 20:44 and often). The second therefore, followed by no new verb, is both superfluous and difficult and should probably be omitted, with LXX.

that Iam he that doth speak: behold, it is I The last words "behold me" are hardly to be taken as obj. of the verb "speak"; they simply repeat the sense of the preceding clause: "They shall know that it is I who speak; here am I" (cf. Ezekiel 5:13).
