'Grains' in the Bible
Do you not fear and reverence Me? says the Lord. Do you not tremble before Me? I placed the sand for the boundary of the sea, a perpetual barrier beyond which it cannot pass and by an everlasting ordinance beyond which it cannot go? And though the waves of the sea toss and shake themselves, yet they cannot prevail [against the feeble grains of sand which God has ordained by nature to be sufficient for His purpose]; though [the billows] roar, yet they cannot pass over that [barrier]. [Is not such a God to be reverently feared and worshiped?]
And I said, What is it? [What does it symbolize?] And he said, This that goes forth is an ephah[-sized vessel for separate grains all collected together]. This, he continued, is the symbol of the sinners mentioned above and is the resemblance of their iniquity throughout the whole land.
One Sabbath He was going along beside the fields of standing grain, and as they made their way, His disciples began to pick off the grains.
