G1492I–εἴδω–eidō

And the apostles and elders came together to consider of this matter.

ἰδεῖν idein “to understand”

Him would Paul have to go forth with him; and took and circumcised him, because of the Jews who were in those quarters: for they all knew that his father was a Greek.

ᾔδεισαν ēdeisan “they knew”

Some therefore cried one thing, and some another: for the assembly was confused, and the greater part knew not why they had come together.

ᾔδεισαν ēdeisan “did know”

Then said Paul, I knew not, brethren, that he is the high priest: for it is written, Thou shalt not speak evil of the ruler of thy people.

ᾔδειν, ēdein “I had known,”

What shall we say then? Is the law sin? By no means. No, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.

ᾔδειν, ēdein “I had known,”

And they shall not teach every man his neighbor, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.

εἰδήσουσίν eidēsousin “will know”
