'Forgotten' in the Bible

Are not five sparrows sold for two pence? and not one of them is forgotten in the sight of God.

and ye have forgotten the exhortation which reasoneth with you as with sons, My son, regard not lightly the chastening of the Lord, Nor faint when thou art reproved of him;

For he that lacketh these things is blind, seeing only what is near, having forgotten the cleansing from his old sins.
