To take care of, to show diligent concern for someone's welfare — implying personal attention and ongoing responsibility. Used by Jesus in the parable of the Good Samaritan to describe the quality of care that defines true neighborliness.
In Luke 10:34–35, the Samaritan 'took care of' the wounded man — paying, staying, and making provision for ongoing care. This is not charity from a distance but incarnational care: entering into another's suffering and bearing the cost. Jesus' use of this word defines the love of neighbor not as sentiment but as sustained, costly action. It is the word that answers the question: 'Who is my neighbor?'
