What does Proverbs 2:7 mean?

Overall, this passage of Proverbs describes the idea of living virtuously; in the context of ancient philosophy, this means pursuing certain attributes, such as wisdom, justice, integrity, and courage. The end result of living a virtuous life is given, in part, in this verse. Those who "walk in integrity" can count on God to act as their shield. The Hebrew term translated "shield" here is mā-gēn, which refers to a "defender," and was sometimes used in reference to the scaly hide of a crocodile. The image is of something which provides a sense of personal security, of safety.

This passage also ties together the ideas of virtuous living and discernment. Discernment can be seen in a well-practiced trait of wisdom, remembering that in Proverbs wisdom is the proper application of knowledge. Simply knowing facts in one's mind is not enough to see good results. We need to apply what we know, in the right way, and at the right time. Often, this is easier said than done. It can require a good dose of courage, and this passage gives us confidence that God is on the side of those who do just that.
