Albert Barnes on Acts 10:7

A devout soldier. A pious man. This is an instance of the effect of piety in a military officer. Few men have more influence; and in this case the effect was seen not only in the piety of his family, but of this attending soldier. Such men have usually been supposed to be far from the influence of religion; but this instance shows that even the labours and disadvantages of a camp are not necessarily hostile to the existence of piety. Comp. Lk 3:14.
