John Gill

For ye are our glory and joy. Or "our joy", as the Syriac, Arabic, and Ethiopic versions read; this is a repetition, and a confirmation of what is before said; and signifies that these saints were then the glory of the apostles, being the seals of their ministry; and whom they gloried of and rejoiced in, and hoped and believed they would be such, as would be their joy and crown in time to come, and for ever. Next: 1 Thessalonians Chapter 3
