'Warn' in the Bible
"Son of man, I have appointed you [as] a watchman for the house of Israel. When you hear a word from my mouth, then you must warn them from me.
{When I say} to the wicked, 'Surely you will die,' and you do not warn him and you do not speak to warn [the] wicked from his wicked way {so that he may live}, that wicked [person] will die because of his guilt, and from your hand I will seek his blood.
And you, if you do warn [the] wicked and he does not turn from his wickedness and from his wicked way, on account of his guilt he will die, and you yourself will have saved your life.
And {when the righteous turns from his righteousness} and does injustice, and I place a stumbling block {before him}, he will die, for you did not warn him. Because of his sin he will die, and his righteousness that he did will not be remembered, and his blood I shall seek from your hand.
And if you warn him, the righteous, not to sin, and [the] righteous does not sin, surely he will live, for he heeded a warning. And you will have saved your life."
"And you, son of man, I have made you a watchman for the house of Israel; if you hear a word from my mouth, then you must warn them from me.
{When I say} to the wicked, 'Wicked [one], you will certainly die,' and you {did not speak} to warn [the] wicked from his way, he, [the] wicked, will die by his guilt, but his blood I will seek from your hand.
But, you, if you warn [the] wicked from his way, to turn from it, and {he does not turn} from his way, he will die by his guilt, and you will have saved your life.
