(1.) Hebrews hatsir, ripe grass fit for mowing (1 Kings 18:5; Job 40:15; Psalm 104:14). As the herbage rapidly fades under the scorching sun, it is used as an image of the brevity of human life (Isaiah 40:6, 7; Psalm 90:5). In Numbers 11:5 this word is rendered "leeks."
(2.) Hebrews deshe', green grass (Genesis 1:11, 12; Isaiah 66:14; Deuteronomy 32:2). "The sickly and forced blades of grass which spring up on the flat plastered roofs of houses in the East are used as an emblem of speedy destruction, because they are small and weak, and because, under the scorching rays of the sun, they soon wither away" (2 Kings 19:26; Psalm 129:6; Isaiah 37:27).
The dry stalks of grass were often used as fuel for the oven (Matthew 6:30; 13:30; Luke 12:28).
