By faith in his name (th pistei tou onomato autou). Instrumental case of pistei (Aleph and B do not have epi) and objective genitive of onomato. His name (to onoma autou). Repeats the word name to make the point clear. Cf. verse Acts 6 where Peter uses "the name of Jesus Christ of Nazareth" when he healed the man. Made strong (esterewsen). Same verb used in verse Acts 7 (and Acts 16:5 ). Nowhere else in the N.T. Old verb from stereo, firm, solid. Through him (di autou). Through Jesus, the object of faith and the source of it. Perfect soundness (oloklhrian). Perfect in all its parts, complete, whole (from olo, whole, klhro, allotment). Late word (Plutarch) once in LXX ( Isaiah 1:6 ) and here alone in the N.T., but adjective oloklhro, old and common ( James 1:4 ; 1 Thessalonians 5:23 ).
