Isaiah 40:15 Behold, the nations are as a a drop in a bucket , And are counted as the small dust on the scales ; Look, He lifts up the isles as a very little thing.
AMP Behold, the nations are like a drop from a bucket and are counted as small dust on the scales; behold, He takes up the isles like a very little thing.
Dust is so insignificant it doesn’t effect the scales , when fruit and meat are being weighed dust wouldn’t increase or decrease the weight .
Ps 103:14 “For He knows our frame; He remembers that we are dust.”
Job 20:11 “His bones are full of his youthful vigor, But it will lie down with him in the dust.”
Proverbs 11:1 “Dishonest scales are an abomination to the Lord, But a just weight is His delight.”
