“The wise man’s path of life leads upward.
Thus he may avoid Sheol below.
Yahweh tears down the house of the proud.
But he maintains the widow’s boundaries.”
The path of the wise man goes up, so that he does not go down to Sheol. This is the common conception that up is good and down is bad. Just like a house, the upstairs are better than the basements. Yahweh would tear down the house of the proud ones, but he would sustain the territory or boundaries of the widows.
