2). He Rejoices In The Delivery Of Himself And His Men (4-7).
D ‘I sought YHWH, and he answered me,
And delivered me from all my fears.
H They looked to him, and were radiant,
And their faces will never be confounded.'
If the heading of the Psalm is seen as an indicator this may well reflect David's relief that his subterfuge before Achish worked. No doubt as he scrabbled on the floor feigning madness he had been flashing pleas to YHWH. And here we learn of his profound gratitude when he safely left the king's presence, delivered from all his fears (the tension must have been huge). His prayers had been answered.
And we can quite understand that when he went back to his companions (1 Samuel 21:5), who must have been waiting in some trepidation, desperately calling on YHWH, and they saw that he had come away with his life, their faces became radiant as they looked to YHWH with praise and gratitude. Compare how the people's faces were to be ‘lightened' in Isaiah 60:5 when they saw God working out His deliverance. And David then adds with confidence that while they remain true to YHWH and His Anointed they will never be confounded. We can compare with this Peter's appearance at the door of the house where people were praying for his deliverance in a similar situation (Acts 12:12-17). They too were filled with joy, and no little amazement.
And for us all it is an indication that if we are loyal to Him, and look to Him, He will deliver us from all our fears, when we seek His face. We too will thus be able to look to Him and be radiant, and be confident that we will never be confounded while He is our Lord. We too will hear His voice saying, ‘Arise, shine, for your light has come, and the glory of YHWH has risen upon you' (Isaiah 60:1; Isaiah 60:5).
