What does the Bible say about death?

Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me. Your rod and your staff, they comfort me.

Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit.

For I am persuaded that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers,

nor height, nor depth, nor any other created thing will be able to separate us from God’s love which is in Christ Jesus our Lord.
