'Dost' in the Bible

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

When thou dost lend thy brother anything, thou shalt not go into his house to secure his pledge.
