to sow: to scatter seed on prepared ground so that a crop will grow
This is the everyday word for planting a field. A farmer breaks up the soil, casts the seed across it, and waits for the harvest. Because that whole cycle of scattering now and reaping later was so familiar, the Bible reaches for the same word to picture other things that work the same way.
The most common stretch is moral: what a person sows is what they will reap. Sow honesty and you gather a real reward; sow wrongdoing and the harvest is trouble. The point is not gardening but consequence, the law that actions ripen into outcomes you cannot dodge.
A second stretch is national. When God promises to sow his people in the land, he means he will plant them there to take root, grow, and multiply, the way a sower fills an empty field. Even scattering Israel among other nations can be described this way, as a planting that will one day bear fruit far from home.
The senses below hold together because they all share one picture: seed goes out, time passes, and a harvest answers for it.
