King James Bible
"When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth."
God curses Cain's agricultural efforts, declaring the soil will resist his farming despite his labor. This reverses the ground's natural productivity, making Cain's former livelihood as a farmer impossible and forcing him to seek sustenance elsewhere. Cain is condemned to perpetual wandering without a fixed home or community. The dual terms emphasize both his status as one fleeing justice and his rootless existence, marking him as permanently alienated from settled society and the stability it provides.
