Charles Ellicott Commentary Acts 15:36

"And after some days Paul said unto Barnabas, Let us return now and visit the brethren in every city wherein we proclaimed the word of the Lord, [and see] how they fare." — Acts 15:36 (ASV)

And some days after Paul said unto Barnabas.—The commonly received chronology of the Acts makes the interval between the Council of Jerusalem and St. Paul’s second missionary journey somewhat more than a year.

Let us go again.—The proposal was characteristic of one whose heart was ever full of the care of all the churches (2 Corinthians 11:28), ever making mention of them in his prayers night and day (Romans 1:9; Ephesians 1:16; Philippians 1:3). We may well believe that it was a desire to know, not only the general condition of the churches, but the spiritual growth of each individual member.
