Those who hunger for righteousness,
Those who thirst for righteousness,
They shall be filled.”
μακάριοι οἱ πεινῶντες καὶ διψῶντες τὴν δικαιοσύνην, ὅτι αὐτοὶ χορτασθήσοντ
The happy, blessed, and fortunate ones (μακάριοι) were those who hungered and thirsted for righteousness (οἱ πεινῶντες καὶ διψῶντες τὴν δικαιοσύνην). They would not go away empty handed. They would be satisfied or filled (ὅτι αὐτοὶ χορτασθήσοντ). Isaiah, chapter 55:1-2 has an invitation to those without money to come to drink and eat. They could have water, wine, milk and bread. They would enjoy themselves at this banquet. Matthew may have been referencing Psalm 107:4-9, where Yahweh had helped a small group of lost Israelites who were hungry and thirsty, while wandering in the desert. He satisfied their thirst and filled their hunger with good food. In their distress, they called out to Yahweh, who heard them. He led them in a straight path to an inhabited town. Thus, they gave thanks to Yahweh. So too, those who hungered and thirsted for righteousness, the right way of doing things, would be satisfied or filled with this righteousness.
