Hebrews 13:5

Let your conversation be without covetousness
Which is an immoderate desire, of riches, an over anxious care for worldly things, attended with dissatisfaction, and discontent with their present state: it discovers itself many ways; in preferring the world to religion; in laying up treasure for a man's own self, without being any ways useful to others; in withholding from himself the necessaries of life, and in making no use of his substance for the glory of God, and the interest of religion: this is a very great evil; it is called idolatry, and is said to be the root of all evil; and is very pernicious to true religion: a believer's conversation should be without it; in his family, for whom he should provide things convenient and honest; and in the world, where he should deal uprightly, and not defraud and overreach; and in the church, where he should be liberal, and generously communicate, upon all occasions; and such a conversation is becoming the Gospel, which is a declaration of things freely given to us of God. The reason of the apostle's mentioning this sin of covetousness is, because the Jews were prone to it, and these believing Hebrews might be inclined to it, and be dissatisfied with their present condition, in which they suffered the spoiling of their goods; and besides, unless this was avoided, the above mentioned duties could not be performed aright, as brotherly love, hospitality, remembering and relieving persons in bonds, and adversity.

And be content with such things as ye have;
or with present things; with present riches, or with present poverty; with present losses and crosses; with present reproaches and afflictions; and contentment with these things shows itself by thankfulness for every mercy, and by submission to the will and providence of God in every state of life: and there are many things which may move and engage unto it; as the consideration of the state and condition men are in, when they come into the world, and will be when they go out of it; the will of God, and the disposition of his providence according to it, which is unalterable; a sense of: their own unworthiness; a view of interest in God and Christ; and an eye to the recompense of reward; as well as the many promises of God to support and supply his: and among the rest, what follows,

for he hath said, I will never leave thee, nor forsake thee;
which is a promise made to Joshua, and belongs to all believers, ( Joshua 1:5 ) which may regard things temporal, as that God will not leave his people in the hands of their enemies, nor forsake them in distress, nor withhold any good thing from them needful for them, but will supply them with the necessaries of life, with which they should be content: and this passage is very pertinently cited for this purpose, and could be easily understood in this sense by the Hebrews; for the Jews explain such places as speak of God's not forsaking men, of the sustenance of them, as ( Psalms 37:25 ) and observe that the word (hbyze) , "forsaking", is never used but with respect to (honrp) , "sustenance" ^F21; though the words may also relate to things spiritual, as that God will not leave them to themselves, to their own corruptions, which would overpower them; nor to their own strength, which is but weakness; nor to their own wisdom, which is folly; nor to Satan, and his temptations, who is an over match for them; nor to the world, the frowns and flatteries of it, by which they might be drawn aside; nor will he leave them destitute of his presence; for though he sometimes hides his face, and withdraws himself, yet not wholly, nor finally; nor will he forsake the work of his own hands, in them, but will perform it until the day of Christ; he will not leave or forsake them, so as that they shall perish; he will not forsake them in life, nor at death, nor at judgment.
