       Abraham formed an alliance with some of the Canaanitish
     princes (Gen. 14:13), also with Abimelech (21:22-32). Joshua and
     the elders of Israel entered into an alliance with the
     Gibeonites (Josh. 9:3-27). When the Israelites entered Palestine
     they were forbidden to enter into alliances with the inhabitants
     of the country (Lev. 18:3, 4; 20:22, 23).
       Solomon formed a league with Hiram (1 Kings 5:12). This
     "brotherly covenant" is referred to 250 years afterwards (Amos
     1:9). He also appears to have entered into an alliance with
     Pharaoh (1 Kings 10:28, 29).
       In the subsequent history of the kingdoms of Judah and Israel
     various alliances were formed between them and also with
     neighbouring nations at different times.
       From patriarchal times a covenant of alliance was sealed by
     the blood of some sacrificial victim. The animal sacrificed was
     cut in two (except birds), and between these two parts the
     persons contracting the alliance passed (Gen. 15:10). There are
     frequent allusions to this practice (Jer. 34:18). Such alliances
     were called "covenants of salt" (Num. 18:19; 2 Chr. 13:5), salt
     being the symbol of perpetuity. A pillar was set up as a
     memorial of the alliance between Laban and Jacob (Gen. 31:52).
     The Jews throughout their whole history attached great
     importance to fidelity to their engagements. Divine wrath fell
     upon the violators of them (Josh. 9:18; 2 Sam. 21:1, 2; Ezek.
     17:16).
