Psalm 91:16 (NKJV):
With long life I will satisfy him, And show him My salvation."

Let's break down the key words here for a clearer understanding:

1. **"Long life" (Hebrew: *'orekh yôm*)**
- Literally means "length of days."
- It implies a life that is full, extended, and blessed by God.
- In biblical terms, it often signifies God's blessing of prosperity and longevity to the faithful.

2. **"Satisfy" (Hebrew: *sābaʿ*)**
- Means to fill, satisfy, or satisfy fully.
- It carries the sense of being completely content or fulfilled.
- God promises to fully satisfy the believer with life, not just mere existence but abundant, fulfilling life.

3. **"Show" (Hebrew: *nātāh*)**
- Means to stretch out, extend, or give.
- Here, God is saying He will extend or reveal His salvation to the person.

4. **"My salvation" (Hebrew: *yeshuʿāti*)**
- Refers to deliverance, rescue, or saving from danger and death.
- It's both a present and future promise of God's saving power—spiritual and physical deliverance.

**Putting it all together:**
God promises that He will give a person who trusts in Him a long, full life filled with satisfaction, and He will also reveal His salvation—His saving help and deliverance—to them.

This verse beautifully captures God's care, blessing, and promise to those who remain faithful and trust in Him.
