'Dost' in the Bible

Not for thy righteousness, or for the uprightness of thine heart, dost thou go to possess their land: but for the wickedness of these nations the LORD thy God doth drive them out from before thee, and that he may perform the word which the LORD sware unto thy fathers, Abraham, Isaac, and Jacob.

When thou dost lend thy brother any thing, thou shalt not go into his house to fetch his pledge.

Thou shalt stand abroad, and the man to whom thou dost lend shall bring out the pledge abroad unto thee.
