'Obscures' in the Bible

Nevertheless, I haven't been silenced because of the darkness, even when thick darkness obscures my vision."

He obscures the view of His throne,spreading His cloud over it.

Who is this who obscures My counselwith ignorant words?

“[You said to me] ‘Who is this that darkens and obscures counsel [by words] without knowledge?’Therefore [I now see] I have [rashly] uttered that which I did not understand,Things too wonderful for me, which I did not know.
