'Barrier' in the Bible

With You I can attack a barrier,and with my God I can leap over a wall.

With You I can attack a barrier,and with my God I can leap over a wall.

Do you not fear Me?This is the Lord’s declaration.Do you not tremble before Me,the One who set the sand as the boundary of the sea,an enduring barrier that it cannot cross?The waves surge, but they cannot prevail.They roar but cannot pass over it.

There was a barrier of 21 inches in front of the recesses on both sides, and the recesses on each side were 10½ feet square.
