Dear Salim, The Bible does not have any direct prohibitions against begging, nor does it have any imperatives or commands that direct believers to beg. The weight of Scripture would support hard work, enterprise, and thrift.
Scripture also supports and commands giving, stewardship, helping, and serving.
Scripture supports taking care of those who are penniless so that they are not reduced to begging. Christians should not harden their hearts to those in need simply because there are some who are dishonest.
