Mercy and truth preserve the king
Which are two good qualifications in a prince; not ruling his
subjects with rigour and cruelty, but with tenderness and
clemency; easing them as much as he can of burdens and pressures;
showing compassion to the distressed, and pardoning delinquents
when the case will admit of it; as also being faithful to his
word, promises, and engagements; inviolably adhering to the laws
and constitution of the nation, and steady in his administrations
of justice; these preserve him in the affections of his people,
and make him safe and secure on his throne; and because of these
the Lord preserves him from his enemies. It maybe rendered,
"grace and truth" F12; and applied to Christ, who is full
of both, and which are said to preserve him, ( Psalms 40:11
) ; and his throne is upholden by mercy;
this explains what is meant by the preservation of him, and what
is the security of his throne and kingdom, which is clemency and
goodness to his subjects.
