3,600. The Fruit of an Ex-Asheira

Hilchos Bikkurim 2:15

If someone sells his property to a non-Jew and later buys it back, he brings first fruits under Biblical law. This is because the non-Jew’s purchase doesn’t create an exemption.

Hilchos Bikkurim 2:16

If a person nullified an asheira (a tree that was served as an idol), one doesn’t bring first fruits from it. This is because first fruits are like Temple sacrifices (and something that was once worshiped is invalid for the Temple).
