Thomas Aquinas, on Heb 13:5

“Let your manners be without covetousness, contented with such things as you have; for he hath said: I will not leave thee, neither will I forsake thee.”

“Then (v. 5) he forbids them to covet external goods, in regard to which one might sin in two ways: in one way by being niggardly; in another way by being covetous. For liberality is a virtue which inclines one to the happy medium between giving and retaining money. As to the first, i.e., niggardliness, he says: Keep your life from love of money [covetousness]. For a covetous person is tenacious; hence, Sirach (10:9) says: 'Nothing is more wicked than the covetous man.' As to the second he says, and be content with what you have. Those who desire to have more than they have, wish to heap up other things, not being content with what they have: 'Having food and clothing, with these we are content' (1 Tim. 6:8). Or in saying, let your life be free of covetousness, he is forbidding avarice in regard to covetousness and niggardliness; but in saying, be content with what you have, he is excluding the root of avarice, namely, anxiety: 'Be not anxious' (Mt. 6:31). For men are not forbidden to be solicitous about things needed for the future, but care and anxiety should not preoccupy their mind. For one who is so preoccupied with anxiety about the future is 'solicitous of the morrow.' Then (v. 5b) he gives the reason for this advice, and it is the reason why we should not be excessively anxious, but should do what lies in our power with trust in God's help: for he has said (Jos. 1:5): 'I will not leave you, without giving you what you need; neither will I forsake you, lest you perish from hunger'; 'I have not seen the just forsaken, not his seed seeking bread' (Ps. 36:25). Or I will not forsake you without freeing you from evil. This causes confidence in the heart so that we can confidently say, 'I will deal confidently and will not fear' (Is. 12:2).”
