Psalms 102:25-27 (ESV Strong's) 25 Of old you laid the foundation of the earth, and the heavens are the work of your hands. 26 They will perish, but you will remain; they will all wear out like a garment.
You will change them like a robe, and they will pass away, 27 but you are the same, and your years have no end.
JESUS
Hebrews 1:8-12 (ESV Strong's) 8 But of the Son he says, “Your throne, O God, is forever and ever, the scepter of uprightness is the scepter of your kingdom. 9 You have loved righteousness and hated wickedness; therefore God, your God, has anointed you with the oil of gladness beyond your companions.” 10 And, “You, Lord, laid the foundation of the earth in the beginning, and the heavens are the work of your hands; 11 they will perish, but you remain;they will all wear out like a garment,12 like a robe you will roll them up, like a garment they will be changed. But you are the same, and your years will have no end.”
