Wanted. That is, lacked, or was in want (see on Luke 15:14). During his ministry at Corinth Paul had exhausted his resources and lacked sufficient means to meet even his barest needs — while ministering to a prosperous church. Their indifference revealed a high degree of thoughtlessness, if not selfishness, and was without excuse. But even then Paul gave the Corinthians no indication of his need.
The situation was remedied, not by the Corinthian believers, as might have been expected, but by the opportune arrival of brethren from Macedonia with a further gift (see Phil. 4:10). The brethren referred to may have been Silas and Timothy (Acts 18:5).
Chargeable. Greek katanarkao, “to be burdensome.” Another form of the Greek word provides the name for a parasite fish that attaches itself to other creatures to secure nourishment from them. As a result the host suffers a state of numbness. Paul had not been a parasite, living off the Corinthians. He had not burdened them financially or otherwise. His ministry had not reduced them to a state of numbness, either spiritually or economically. To the contrary, he had inspired them, imparted life to them, invigorated them.
