▪ The idea of making a payment (though not in advance but ex post) is also already present, as a special meaning among other more general ones, in the Akk G-stem
šalāmu ‘[…];
1
6. to obtain financial satisfaction, receive full payment’ and in the corresponding D-stem
šullumu ‘[…] 12. to pay in full, repay, compensate, to deliver in full, make good, make restitution, make up a loss, repair a damage right a wrong’.
▪ According to Zimmern1914, this Akk
šullumu was taken, with identical meaning as a technical term, into Hbr as
šillēm, Aram
šallem (and Ar ↗
sallama, probably from the Aram form).
