What does Leviticus 23:22 mean?

When you're harvesting your fields, don't cut right up to the edges, and don't go back to pick up what you missed. Leave that for people who are struggling and for outsiders living among you. I'm the Lord your God. Leviticus 23:22 - Modern Text Bible

(This verse tells people to leave some of their crops for the poor and immigrants, reminding them that God cares about everyone, especially those in need.)
