And do not lean on your own understanding.
In all your ways acknowledge Him,
And He will make your paths straight.
The word "trust" is used in the OT in (1) literal physical sense: to physically lean upon something for support and (2) figurative sense: to rely upon someone or something for help or protection
The “heart” functions as a metonymy of subject encompassing mind, emotions and will
"Acknowledge" The verb yadah, “to know” includes mental awareness of who God is and the consequential submission to his lordship. To know him is to obey him.
(Notes adapted from the NET Bible)
Teach me to trust You with all that I am, Father - mind, emotions and will. Show me what it is to acknowledge You in all things, in all of life.
