to apply salt to something, to restore the flavor to salt (a causative derivative of ἅλς ‘salt,’ 5.25) to cause something to taste salty In MAT 5:13 one may employ a causative such as ‘how will the salt be made salty again’ or ‘how can one cause the salt to return.’ In MRK 9:49 the meaning is particularly obscure. According to OT requirements sacrifices were to be salted (LEV 2:13), and it may be that in MRK 9:49 the fire is regarded as an equivalent of salt and as a symbol of suffering and sacrifice by which the disciple is tested.
1 MAT 5:13 · MRK 9:49 It would be possible to analyze the occurrence of ἁλίζω in MAT 5:13 and MRK 9:49 as representing two quite distinct meanings, in the first instance ‘to restore the taste of salt,’ and in the second instance ‘to cause something to taste salty.’ However, this type of distinction does not seem to be necessary, for one may define the meaning of ἁλίζω as ‘to cause something to taste salty.’ This would then apply either to salt itself which has previously lost its salty flavor or to a sacrifice which needs to be salted. However, as already noted, the meaning of ἁλίζω in MRK 9:49 is extremely obscure and can only be understood in a highly figurative sense.
