'Certain' in the Bible

Then certain of the elders of Israel came to me [seeking an oracle from God] and sat down before me.

In the seventh year, in the fifth month, on the tenth of the month [after the beginning of the exile in Babylon], certain of the elders of Israel came to inquire of the Lord and sat down before me.

‘It is sharpened to make a slaughter,Polished to flash and glimmer like lightning!’Shall we then rejoice [when such a disaster approaches]? But it rejects and views with contempt the scepter of My son [Judah].
