'Forgettest' in the Bible

When thou reapest thy harvest in thy field, and forgettest a sheaf in the field, thou shalt not return to fetch it; it shall be for the stranger, for the fatherless, and for the widow; that Jehovah thy God may bless thee in all the work of thy hands.

The Rock that begat thee thou forgettest, And neglectest God who formeth thee.
