BRI ; Matt 26:26; Mark 14:22; Luke 22:19. The term bread is often used for food or provisions in general. Bread-corn, Isa 28:28, is used for wheat, barley, or any other grain from which bread was made. The figurative expressions bread of sorrows, Ps 127:2, and bread of tears, Ps 80:5, may denote that the suffering of sorrow and the shedding of tears had become as much a part of the portion of every day as one's daily bread. So the bread of
wickedness, Prov 4:17, and bread of deceit, Prov 20:17, denote not only a living or estate obtained by fraud and sin, but that to do wickedly is as much the portion of a wicked man's life as to eat his daily bread.
