Psalms 86:11-13

Verse 11

Teach me thy way - Instruct me in the steps I should take; for without thy teaching I must go astray.

Unite my heart - יחד לבבי yached lebabi, join all the purposes, resolutions, and affections of my heart together, to fear and to glorify thy name. This is a most important prayer. A divided heart is a great curse; scattered affections are a miserable plague. When the heart is not at unity with itself, the work of religion cannot go on. Indecision of mind and division of affections mar any work. The heart must be one, that the work may be one. If this be wanting, all is wrong. This is a prayer which becomes the mouth of every Christian.
Verse 12

I will praise thee - with all my heart - When my heart is united to fear thy name, then shall I praise thee with my whole heart.
Verse 13

Thou hast delivered my soul from the lowest hell - This must mean more than the grave; a hell below hell - a place of perdition for the soul, as the grave is a place of corruption for the body.
