Adam Clarke's Bible Commentary Verse 8. He saved them for his name's sake ] wm [ml lemaan shemo, "on account of his name;" to manifest his own power, goodness, and perfections. There was nothing which he could draw from them as a reason why he should save them; therefore he drew the reason from himself.
There is a singular gloss in the old Psalter on this verse: "Whan thai cam oute of Egypt to the rede Se, whare thai were closed on a syde with a hylle that na man mygt passe: on another side was the rede See: behynde tham was men of Egypt foluand; and for this thai began to gruch, forgetand Gods mygt: bot than he safed tham, depertand the Se in twelfe, to ilk kynde of Isrel a passage." It seems as if this author thought there were twelve passages made through the Red Sea, that each tribe should have a passage to itself.
Matthew Henry Commentary
Verses 6-12 - Here begins a confession of sin; for we must acknowledge that the Lor has done right, and we have done wickedly. We are encouraged to hop that though justly corrected, yet we shall not be utterly forsaken God's afflicted people own themselves guilty before him. God is distrusted because his favours are not remembered. If he did not sav us for his own name's sake, and to the praise of his power and grace we should all perish.
