More Translations »

seal (n.1)

"design stamped on wax," c.1230, from O.Fr. seel (Fr. sceau), from V.L. *sigellum (cf. It. suggello, Sp. sello, also O.Fris., M.H.G. sigel, Ger. Siegel), from L. sigillum "small picture, engraved figure, seal," dim. of signum "mark, token" (see sign). An earlier borrowing directly from L. is represented by O.E. insigel. Sealing-wax is attested from c.1300. Seal point "dark brown marking on a Siamese cat" is recorded from 1934.

seal (n.2)

"mammal with flippers," O.E. seolh "seal," from P.Gmc. *selkhaz (cf. O.N. selr, Swed. sjöl, M.L.G. sel, M.Du. seel, O.H.G. selah), of unknown origin, perhaps a borrowing from Finnic.

seal (v.)

"to fasten with (or as with) a seal," c.1225, from seal (n.1). Meaning "to place a seal on (a document)" is recorded from 1338; sense of "to close up with wax, lead, cement, etc." is attested from 1661, from the notion of wax seals on envelopes. To seal one's fate (1810) probably reflects the notion of a seal on an execution warrant.

Seal

commonly a ring engraved with some device (Gen. 38:18, 25). Jezebel "wrote letters in Ahab's name, and sealed them with his seal" (1 Kings 21:8). Seals are frequently mentioned in Jewish history (Deut. 32:34; Neh. 9:38; 10:1; Esther 3:12; Cant. 8:6; Isa. 8:16; Jer. 22:24; 32:44, etc.). Sealing a document was equivalent to the signature of the owner of the seal. "The use of a signet-ring by the monarch has recently received a remarkable illustration by the discovery of an impression of such a signet on fine clay at Koyunjik, the site of the ancient Nineveh. This seal appears to have been impressed from the bezel of a metallic finger-ring. It is an oval, 2 inches in length by 1 inch wide, and bears the image, name, and titles of the Egyptian king Sabaco" (Rawlinson's Hist. Illus. of the O.T., p. 46). The actual signet-rings of two Egyptian kings (Cheops and Horus) have been discovered. (See SIGNET.) The use of seals is mentioned in the New Testament only in connection with the record of our Lord's burial (Matt. 27:66). The tomb was sealed by the Pharisees and chief priests for the purpose of making sure that the disciples would not come and steal the body away (ver. 63, 64). The mode of doing this was probably by stretching a cord across the stone and sealing it at both ends with sealing-clay. When God is said to have sealed the Redeemer, the meaning is, that he has attested his divine mission (John 6:27). Circumcision is a seal, an attestation of the covenant (Rom. 4:11). Believers are sealed with the Spirit, as God's mark put upon them (Eph. 1:13; 4:30). Converts are by Paul styled the seal of his apostleship, i.e., they are its attestation (1 Cor. 9:2). Seals and sealing are frequently mentioned in the book of Revelation (5:1; 6:1; 7:3; 10:4; 22:10).
