The Hebrew verb nasak has two distinct ranges of meaning: (1) to pour out a liquid offering (libation) to God or idols, and (2) to cast or overlay metal, and (3) to weave or set in place. In sacrificial contexts it refers to pouring out drink offerings. In royal contexts it refers to God's sovereign appointment of His king.
The drink offering (nesek) was a liquid sacrifice poured out alongside grain and burnt offerings (Numbers 15:1-10) — the final element completing the worship sequence. Paul uses this imagery: "I am already being poured out like a drink offering" (2 Timothy 4:6; Philippians 2:17) — framing his martyrdom as an act of worship. More strikingly, Psalm 2:6 uses a form of nasak: "I have installed (nasak) my king on Zion" — God sovereignly pouring out / establishing His anointed king, pointing to Christ's royal inauguration.
