He will not let my foot slip

I lift up my eyes to the hill--
where does my help come from?
My help comes from the LORD,
the Maker of heaven and earth.

He will not let you foot slip --
he who watches over you will not slumber;
indeed, he who watches over Israel will neither slumber nor sleep.

The LORD watches over you --
the LORD is your shade at your right hand;
the sun will not harm you by day,
nor the moon by night.

The LORD will keep you from all harm --
he will watch over your life;
the LORD will watch over your coming and going both now and forevermore.

Ps 121

I will wait for You to move
For Your mighty hand to save
When the trouble water rise
You are my hiding place

i can't keep me from stumbling and falling
but You can.
