get in the way of sth;block
try to prevent sth
"His brother blocked him at every turn"
"obstruct the path"
"The thick curtain blocked the action on the stage"
"The trees obstruct my view of the mountains"
Both Sin, and Death,..obstruct the mouth of Hell..and seal up his ravenous Jawes.
The sidewalks are obstructed by hobbling women.
