Stablish thy word unto thy servant— Make good thy word unto thy servant; which will issue in thy fear. Which will be thy fear; i.e. thy honour; it will turn to thy honour. There is mercy with thee, therefore shalt thou be feared; i.e. honoured; this would be a foundation of homage to God. So here God's fidelity would make him feared, and gain him honour and homage. Mudge.
