Before the Babylonian exile (see Deyling, Observ. 3. 222 sq., also in Ugolini Thesaur. 28) the Hebrews had and knew no regularly stamped money, but generally made use of a currency in traffic consisting of uncoined shekels (or talents) of silver, which they weighed out to one another ( Genesis 23:16;  Exodus 22:17;  2 Samuel 18:12;  1 Kings 20:39;  Jeremiah 32:9 sq.; comp. Pliny, 33:13), just as among other nations in most ancient times uncoined metal served for money ( A Elian, Var. Hist. 12:10; Strabo, 3. 155), and even to this day the Chinese make their commercial transactions by means of silver bars (Rosenm Ü ller, Morgenl . 1:98; see Sperling, De Nummis Non Cusis , in Ugolini Thesaur. 28). Among the earliest Hebrews, but not afterwards (Crusius, De origin ib. pecunioe a pecore ante nummum sign. Petropol. 1748), an ox or other animal (comp. Pliny; 33:3) was traded instead of cash (see Michaelis, De siclo ante ex'l. Babyl. in the Comment. Soc. Gott. 2:1752, § 1). Yet already in the time of Abraham there circulated in hither Asia, as it seems, silver ingots ( קְשַׁיטָה ,  Genesis 33:19;  Joshua 24:32; see Gesenius, Thes. Heb. p. 1241; Bertheau, p. 24; Tuch, Gen . p. 399, 472) of a determined weight, which was probably indicated by marks ( Genesis 23:16;  Genesis 43:21) stamped upon them (so the Targum of Jonathan explains the former passage by פרקמטיא , i.e. Πραγματεία ). (See Kesitah). Even under the regularly organized Hebrew state small silverpieces (comp, Ἀργύρια , silverling) may have passed in exchange (as among their Phoenician neighbors; but see Herod. 1:94; Philostr. Her. 10:1), although destitute of national authority (see  1 Samuel 9:8; comp.  Exodus 30:13;  Leviticus 27:3 sq.;   Copyright StatementThese files are public domain.
