This verb means to plow or till soil for agriculture. Jesus asks rhetorically if a servant 'plowing' returns from the field expecting immediate thanks (Luke 17:7). Paul quotes the principle that one who 'plows' should plow in hope of sharing the harvest (1 Cor 9:10, twice). The agricultural image illustrates spiritual principles about service, labor, and rightful expectation of provision. Plowing represents the hard preparatory work that anticipates future reward, foundational to Paul's argument about supporting gospel workers.
