'Praise' in this verse is the present tense, see Note h, ch. 6.13. 'Laud' is the aorist of the same verb, but with a strengthening preposition prefixed, giving the sense of 'let them have him lauded.'
Or 'for,' pros with accusative: see Note f, Eph. 4.12.
Or 'whenever I go.' It is the subjunctive; i.e. not a fact assumed to happen, though not yet come; nor treated as improbable, though it may happen, but between the two -- the possibility and intention expressed. The sentence does not follow grammatically, but is interrupted by 'for I hope,' &c.
