 Glean
    The corners of fields were not to be reaped, and the sheaf
    accidentally left behind was not to be fetched away, according
    to the law of Moses (Lev. 19:9; 23:22; Deut. 24:21). They were
    to be left for the poor to glean. Similar laws were given
    regarding vineyards and oliveyards. (Comp. Ruth 2:2.)
