1. "Bread as ordinary daily food. Ancient man of Bible times had a simple diet including the important element of bread. The early Hebrews counted it along with water as vital for daily existence, a food which was normally eaten at home or taken on a journey. Without it, the Israelite felt his life was in danger. Bread was counted as the staff of life (called “the staff of bread,” “the whole stay of bread”).
The NT emphasis is placed on the necessity of bread for the daily life, as seen in the ministry of Jesus when He quoted a portion of Deuteronomy 8:3 to Satan and later showed concern for the food needs of the 5,000 and of the 4,000.
The reference in the Lord’s Prayer to bread certainly stresses the human dependence on a daily supply of bread (cf. also the manna supplied in the wilderness).”
