And they that had eaten were about five thousand men, beside women and children.

People's New Testament

14:21 Five thousand men. Thus there was one loaf to every thousand men. Christ is the bread if life, satisfying the hunger of the soul for love, forgiveness, immortality, usefulness, progress, knowledge. He gives that bread to his disciples and bids them to distribute it to the multitude. Such is its blessed and divine nature that the more they distribute to hungry, famishing souls, the more they have remaining for themselves.

Matthew Henry's Concise Commentary

14:13-21 When Christ and his word withdraw, it is best for us to follow, seeking the means of grace for our souls before any worldly advantages. The presence of Christ and his gospel, makes a desert not only tolerable, but desirable. This little supply of bread was increased by Christ's creating power, till the whole multitude were satisfied. In seeking the welfare of men's souls, we should have compassion on their bodies likewise. Let us also remember always to crave a blessing on our meals, and learn to avoid all waste, as frugality is the proper source of liberality. See in this miracle an emblem of the Bread of life, which came down from heaven to sustain our perishing souls. The provisions of Christ's gospel appear mean and scanty to the world, yet they satisfy all that feed on him in their hearts by faith with thanksgiving.
