{From stumbling} (aptaistous). Verbal from ptai(935c), to
stumble ( Jas 3:2  2Pe 1:10 ), sure-footed as of a horse that
does not stumble (Xenophon), and so of a good man (Epictetus,
Marcus Antoninus). {Before the presence of his glory}

like st(8873)ai here (first aorist active infinitive) and also
am(936d)ous as here, but am(936d)(8874)os in  2Pe 3:14 . {In exceeding
joy} (en agalliasei). See  Lu 1:14 .
