Ruth 2:4 - Joseph Benson’s Commentary on the Old and New Testaments

And said unto the reapers, The Lord be with you, &c. Such was the piety of ancient times, that it manifested itself even in men's civil conversation and worldly transactions, and induced them to pray to God for a blessing on the labours of those whom they saw to be honestly and usefully employed, who were wont in return to pray in a similar manner for them. The Lord be with you; and the Lord bless you This was the beautiful language of religion in those days; too little known, alas! in ours.
