Which OT laws are "external regulations"?
What Old Testament laws are considered "external regulations" in Hebrews 9:10?

Hebrews 9:10 in Focus

“They consist only in food and drink and special washings—external regulations imposed until the time of reform.” (Hebrews 9:10)


What “external regulations” means

• The Greek phrase dikaiōmata sarkos speaks of rules that touch the body—outward actions, physical rituals, material substances.

• They were divinely commanded but intentionally temporary, pointing forward to a fuller work God would accomplish in Christ (cf. Hebrews 9:9; 10:1).


Key categories of these regulations

• Food laws

– Clean/unclean animals: Leviticus 11; Deuteronomy 14:3-21

– Forbidden fat and blood: Leviticus 3:16-17; 7:22-27

– Portions reserved for priests: Leviticus 7:31-34

• Drink regulations

– Drink offerings poured with sacrifices: Numbers 15:5-10; 28:7-8

– Priests prohibited from wine while ministering: Leviticus 10:9

– Nazirite vow bans wine, vinegar, grapes: Numbers 6:2-4

• Special washings (baptismois, “immersions”)

– Priests wash before entering the tent: Exodus 30:17-21

– Objects sprinkled with blood or water: Exodus 29:21; Numbers 19:18-19

– Purifications after childbirth, disease, or bodily discharge: Leviticus 12–15

– Day-of-Atonement washings: Leviticus 16:4, 24

• Additional bodily ordinances tied to the tabernacle

– Daily, weekly, monthly, and yearly sacrifices: Exodus 29:38-42; Numbers 28–29

– Ritual meals eaten inside the sanctuary: Leviticus 6:16-18; 24:5-9


Representative Old Testament passages

• Food: “You may eat any animal with a split hoof… but of those that chew the cud or have split hooves you are not to eat…” (Leviticus 11:3-4)

• Drink: “Its drink offering shall be a quarter hin of wine.” (Numbers 28:7)

• Washing: “Aaron and his sons shall wash their hands and feet from it.” (Exodus 30:19)


Purpose behind the regulations

• To distinguish Israel as holy (Leviticus 20:24-26).

• To teach the need for purity before approaching God (Leviticus 19:2).

• To serve as symbolic shadows—“a reminder of sins” until the perfect sacrifice came (Hebrews 10:3-4).


Their temporary nature

Hebrews 9:10 says they lasted “until the time of reform.”

• That time arrived in Christ, who “entered the greater and more perfect tabernacle… by His own blood” (Hebrews 9:11-12).

• The same chapter contrasts “the blood of goats and bulls” that sanctify the flesh (v. 13) with Christ’s blood that “cleanse[s] our conscience” (v. 14).


Fulfillment in Christ

Colossians 2:16-17—food, drink, and festivals are “a shadow of the things to come, but the body belongs to Christ.”

Mark 7:18-19—Jesus “declared all foods clean,” signaling the completion of dietary shadows.

Titus 3:5—salvation now rests on “the washing of rebirth and renewal by the Holy Spirit,” not repeated ritual washings.


Takeaway

The “external regulations” in Hebrews 9:10 refer to the Old Testament commands about food, drink offerings, and ritual washings—physical, flesh-oriented ordinances bound to the tabernacle system. They were good gifts for a season, teaching holiness and prefiguring the ultimate cleansing accomplished once for all by the Messiah.
