beg'-er-li (ptochos): The word has the thought of "to crouch" or "cringe," such as is common with professional beggars. It is used in Matthew 5:3 and Galatians 4:9, and in both cases means complete spiritual destitution. As used in Galatians it expresses the contrast between their present condition and the former estate, toward which he says they are again tending. Paul has in mind both the Jewish and heathen systems of religion with all their outward show. He therefore here emphasizes to the immeasurable superiority of the riches and liberty in Christ. He further expresses this same thought of the law in Romans 8:3 and Hebrews 7:18. In view of the wretchedness of the condition indicated by the word "beggarly," he states his astonishment that they should so little appreciate the liberty and riches which they now enjoy as even to think of going back the former condition.

Acts 17:18 A few of the Epicurean and Stoic philosophers also encountered him. Some of them asked, "What has this beggarly babbler to say?" "His business," said others, "seems to be to cry up some foreign gods." This was because he had been telling the Good News of Jesus and the Resurrection. (WEY)
Galatians 4:9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? (KJV ASV DBY WBS RSV)
