Keil & Delitzsch, on Judg 13:18

“And he answered him: Why askest thou my name, which is wonderful?”

“The angel replied, "Why askest thou then after my name? truly it is wonderful." The Kethibh פלאי is the adjectival form פּלאי from פּלא, for which the Keri has פּלי, the pausal form of פּלי (from the radical פּלה = פּלא). The word therefore is not the proper name of the angel of the Lord, but expresses the character of his name; and as the name simply denotes the nature, it expresses the peculiarity of his nature also. It is to be understood in an absolute sense, - "absolutely and supremely wonderful" (Seb. Schmidt), - as a predicate belonging to God alone (compare the term "Wonderful" in Isa 9:6), and not to be toned down as it is by Bertheau, who explains it as signifying "neither easy to utter nor easy to comprehend."”
