An inheritance may be gotten hastily at the beginning; but the end thereof shall not be blessed.
– Proverbs 20:21
[T]he word for inheritance means just that, and the word for hastily means in a hurry. Many infer some unscrupulous method of gain, and Proverbs does speak to that (Proverbs 13:11; 28:8). The emphasis in this proverb seems to be on the haste, “Easy come; easy go.” What is gained quickly can be lost quickly, and often is (Proverbs 28:20, 22). What is gained quickly is gained without also gaining wisdom. Wisdom does not come quickly. Though wisdom is accessible to the simple (Proverbs 9:4, 16), it’s not just lying about but rather is stored up for those who seek it (Proverbs 2:1-7). To acquire wisdom you must watch daily at wisdom’s gates (Proverbs 8:34), receive instruction and correction (Proverbs 3:11; 9:9; 10:8; 13:10; 17:10), and understand its value enough to be willing to pay a high price for it (Proverbs 17:16; 23:23). You also have to turn from your wisdom in order to acquire true wisdom (Proverbs 3:7; 26:12). To exhaust yourself to gain wealth is to be wise in your own eyes (Proverbs 23:4). So this inheritance is not blessed because it is gained by vanity in a hurry.
