Mattaniah, Bakbukiah, Obadiah, Meshullam, Talmon, and Akkub were gatekeepers keeping watch at the storehouses of the gates.

The gates of the rivers [surrounding Nineveh] are openedAnd the palace [of sun-dried brick] is dissolved [by the torrents].

but their plot became known to Saul. They were also watching the city’s gates day and night so they could kill him;

The very night before Herod was to bring him forward, Peter was sleeping between two soldiers, bound with two chains, and sentries were in front of the door guarding the prison.

And when the blood of Your witness Stephen was being shed, I also was standing nearby approving and consenting [to his death], and guarding the coats of those who were killing him.’

Obey your [spiritual] leaders and submit to them [recognizing their authority over you], for they are keeping watch over your souls and continually guarding your spiritual welfare as those who will give an account [of their stewardship of you]. Let them do this with joy and not with grief and groans, for this would be of no benefit to you.
