Only be strong and very courageous to ensure that you obey all the instructions that my servant Moses gave you turn neither to the right nor to the left from it so that you may succeed wherever you go.

As the Sabbath approached and it began to get dark at the gates of Jerusalem, I gave word to shut the gates, charging that they should not be opened until after the Sabbath. I stationed some of my men at the gates to ensure that no loads would be brought in on the Sabbath day.

The king is strong; he loves justice. You ensure that legal decisions will be made fairly; you promote justice and equity in Jacob.

Ensure your servant's well-being. Don't let the proud oppress me.

if a wicked man restores a pledge, pays back what he has taken by robbery, walks by the statutes which ensure life without committing iniquity, he shall surely live; he shall not die.
