A good tree is not able to bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Bible other translations

“tree.” Although the illustration that Jesus is using certainly applies to literal trees, the illustration is made more powerful and relevant because in the Bible the powerful people in a kingdom were sometimes referred to as “trees,” something that would not have been missed by Jesus’ audience (cp. Judges 9:8-15; Song of Solomon 2:3; 7:8; Isa. 56:3; Ezek. 17:22-24; Dan. 4:10, 22; Zech. 4:3-14; 11:1-3; Luke 3:9; Rom. 11:16-24). Calling people “trees” is usually the figure of speech hypocatastasis. [For an explanation of the figure of speech hypocatastasis, see commentary on Revelation 20:2].
