Divrey Hayamim Bais 20:36 In-Context

34 Now the rest of the acts of Yehoshaphat, harishonim and ha’acharonim, hinei, they are written in the Annals of Yehu ben Chanani, who is recorded in the Sefer of the Melachim of Yisroel.

35 And after this did Yehoshaphat Melech Yehudah join himself in alliance with Achazyah Melech Yisroel, who did very wickedly;

36 And he joined himself with him to make oniyot (ships) to go to Tarshish, and they made the oniyot in Etzyon-Gever.

37 Then Eliezer ben Dodavahu of Mareshah prophesied against Yehoshaphat, saying, Because thou hast joined thyself in alliance with Achazyahu, Hashem hath wrecked thy ma’asim. And the oniyot were wrecked, that they were not able to sail to Tarshish. [T.N. Yehoshaphat had a weakness for entangling himself with non-believers and suffering the consequences.]
