'Stand in' in the Bible

Ye have not gone up into the gaps, neither made up the hedge for the house of Israel to stand in the battle in the day of the LORD.

And I sought for a man among them, that should make up the hedge, and stand in the gap before me for the land, that I should not destroy it: but I found none.

And in controversy they shall stand in judgment; and they shall judge it according to my judgments: and they shall keep my laws and my statutes in all mine assemblies; and they shall hallow my sabbaths.
