Hiding place or Boulder

The Holy can be either a Hiding Place or a Boulder in your way. Is. 8
I have been chewing on this phrase for almost a month now. It slides in and out of my thinking, and every time it gives me pause. Don't fear what they fear...Don't take on their worries.
This passage in Isaiah in context is warning Israel...The King of Assyria and all his power..he is coming like a flood.
Form a plan and it will be thwarted; make a respolve, and it shall nor be carried out. Call not alliance what this people call alliance, and fear not, nor stand in awa of what they fear. Yet He shall be a snare, an obstacle, a boulder in the way.
Protection in either case. We don't like the boulder...interesting that not only is He a obstacle, He is also a snare. I pray for open doors, straight paths, easy directions. Maybe we should also pray for the Holy Boulder...When things are not working out the way we think they should...like there seems to be something in the way...maybe the Holy is keeping us from something...teaching us to wait...teaching us that forward is not always the best direction.
