Ben Sira 11:20

20 Be stedfast in thy covenant, and be conversant therein, and wax old in thy work.

Ben Sira 11:20 In-Context

18 There is that waxeth rich by his wariness and pinching, and this his the portion of his reward:
19 Whereas he saith, I have found rest, and now will eat continually of my goods; and yet he knoweth not what time shall come upon him, and that he must leave those things to others, and die.
20 Be stedfast in thy covenant, and be conversant therein, and wax old in thy work.
21 Marvel not at the works of sinners; but trust in the Lord, and abide in thy labour: for it is an easy thing in the sight of the Lord on the sudden to make a poor man rich.
22 The blessing of the Lord is in the reward of the godly, and suddenly he maketh his blessing flourish.
