Is tithing still relevant in our days?

There is an ongoing debate as to whether Christians are obliged to pay a tenth of their income as tithes. Some people including Christians view the practice as having outlived its usefulness and went away with the Old Testament and therefore could be called “a spiritual 419” being orchestrated by churches that still mandate its collection from their members. It is thought tithe has outlived its usefulness. The reason being that the origin of tithing it is believed was to do with the need to make provision for the Family of Levi who were made priests without land for cultivation. Hence the Levites had no inheritance when the Israelis returned from bondage in Egypt. Ten percent each of the other eleven tribes of Israel was therefore to be apportioned to carter for the needs of the Levites who dedicated all their efforts and time serving and doing the things of God. Today, however priests work and earn very huge income so is necessary for them to continue to tax each church member extra ten percent to take care of their needs?
