Though I walk through the valley of the shadow of death, I will fear no evil; for You are with me. Psa 23:4a
I have looked up the definitions and roots of each word and phrase. This element of the structure could be expanded to say:
Even if I come to, whether I am brought to it by the actions of others, or whether it is the proper destination of my path in living an unwise manner of life, the deep valley overshadowed by death, of very thick darkness so that I can not see my way, I will not tremble or be afraid of the wickedness of others in acting against me, of calamity or deep distress, or the outcome of the worst case scenario. Fear would be a reasonable response if I were facing this valley alone; however, I am not alone. Yehovah, whose name means, Deliverer, Redeemer, Releaser from bondage, Restorer of those who are estranged to Himself; the Creator of the universe, so He who has the ability to act on my behalf; the Ruler of the universe, so He who has the authority to act on my behalf, yes, even You are with me, an active participant in my life, whose presence accompanies me, and is my constant companion no matter my circumstances.
The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined. Isa 9:2
And that light, is Jesus Christ, our Lord.
“For lo, I am with you always, even to the end of the age.” Mat 28:20
