'Dost' in the Bible

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

When thou dost lend thy neighbor any manner of loan, thou shalt not go into his house to fetch his pledge.

Thou shalt stand without, and the man to whom thou dost lend shall bring forth the pledge without unto thee.
