Commentaries:
Robertson's Word Pictures (NT)
So the father knew (egnw oun o pathr). Second aorist active indicative of ginwskw. Inferential use of oun.
Himself believed (episteusen autov). Not just the word of Jesus (verse John 4:50), but complete faith in Jesus himself as the Messiah, absolute use of pisteuw as in John 1:7.
And his whole house (kai h oikia autou). All his family, the first example of a whole family believing in Jesus like the later case of Crispus (Acts 18:8).
