Charles H. Spurgeon on Psalms 119:46

I will speak of thy testimonies also before kings. Before came to the crown kings were sometimes his judges, as Saul and Achish: but if he were called before them to give a reason of the hope that was in: him, he would speak of God's testimonies, and profess to build his hope upon them, and make them his council, his guard, his crown, his all. We must never be afraid to own our religion, though it should expose us to the wrath of kings, but speak of it as that which we will live and die by, like the three children before Nebuchadnezzar, Daniel 3:16 Acts 4:20. After David came to the crown kings were sometimes his companions, they visited him, and he returned their visits; but he did not, in complaisance to them, talk of everything but religion for fear of affronting them, and making his converse uneasy to them: no, God's testimonies shall be the principal subject of his discourse with the kings, not only to show that he was not ashamed of his religion, but to instruct them in it, and bring them over to it. It is good for kings to hear of God's testimonies, and it will adorn the conversation of princes themselves to speak of them. Matthew Henry.
