'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.

Wherefore hidest thou thy face, and forgettest our affliction and our oppression?

and forgettest Jehovah thy Maker, who hath stretched out the heavens, and laid the foundations of the earth; and thou art afraid continually all the day because of the fury of the oppressor, when he prepareth to destroy? And where is the fury of the oppressor?
