Praise thee, i.e. worship thee; one eminent duty of God's worship being put for all, as is frequent in Scripture. With uprightness of heart; or, with a right mind or heart; in a right manner, so as may be acceptable to thee, and beneficial to myself. When I shall have learned thy righteous judgments; when by thy good Spirit I shall be more fully instructed in the meaning of thy word; which is the only rule of thy worship; for want of a sound knowledge whereof many persons run into superstitious or erroneous practices.
