John Chrysostom

"Now these," it says, "were more noble than those in Thessalonica": i.e. they were not men practising base things, but some were convinced, and the others who were not, did nothing of that sort. "Daily," it says, "searching the Scriptures whether these things were so:" not merely upon a sudden impetus or burst of zeal. "More noble," it says: i.e. in point of virtue.

Theophylact of Ohrid

When he says "daily examining the Scriptures, whether these things were so," he means that they searched the Scriptures not as unbelievers (for they had already believed), but as those who did not know the prophetic traditions. Searching the Scriptures and finding that the events concerning the Lord's incarnation agreed with the words of the ancient prophets, they were through this even more strengthened in the faith.

Bede

These people were nobler than those who are in Thessalonica. He speaks of the nobility of soul which they had displayed in hearing and scrutinizing the word.
