They were not to oppress a poor and distressed labourer, by withholding his wages. This command is repeated here from Lev 19:13, with special reference to the distress of the poor man. “And to it (his wages) he lifts up his soul:” i.e., he feels a longing for it. “Lifts up his soul:” as in Psa 24:4; Hos 4:8; Jer 22:27. On Deu 24:15, see Deu 15:9 and Jam 5:4.
