Hemlock

Listen from:
1. laanah, “wormwood:” used only in a figurative sense for bitterness or poison (Amos 6:1212Shall horses run upon the rock? will one plow there with oxen? for ye have turned judgment into gall, and the fruit of righteousness into hemlock: (Amos 6:12)). It is translated WORMWOOD (Deut. 29:1818Lest there should be among you man, or woman, or family, or tribe, whose heart turneth away this day from the Lord our God, to go and serve the gods of these nations; lest there should be among you a root that beareth gall and wormwood; (Deuteronomy 29:18); Prov. 5:44But her end is bitter as wormwood, sharp as a twoedged sword. (Proverbs 5:4); Jer. 9:1515Therefore thus saith the Lord of hosts, the God of Israel; Behold, I will feed them, even this people, with wormwood, and give them water of gall to drink. (Jeremiah 9:15); Jer. 23:1515Therefore thus saith the Lord of hosts concerning the prophets; Behold, I will feed them with wormwood, and make them drink the water of gall: for from the prophets of Jerusalem is profaneness gone forth into all the land. (Jeremiah 23:15); Lam. 3:15,1915He hath filled me with bitterness, he hath made me drunken with wormwood. (Lamentations 3:15)
19Remembering mine affliction and my misery, the wormwood and the gall. (Lamentations 3:19)
; Amos 5:77Ye who turn judgment to wormwood, and leave off righteousness in the earth, (Amos 5:7)). It corresponds with ἄψινθος in Revelation 8:1111And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter. (Revelation 8:11).
2. rosh, some poisonous plant expressive of bitterness or poison (Hos. 10:44They have spoken words, swearing falsely in making a covenant: thus judgment springeth up as hemlock in the furrows of the field. (Hosea 10:4)). The word is elsewhere translated “gall,” “poison,” and “venom.” The common hemlock is the conium maculatum; the water hemlock the cicuta virosa.
