'Distinction' in the Bible

and He made no distinction between us and them, cleansing their hearts by faith.

even the righteousness of God through faith in Jesus Christ for all those who believe; for there is no distinction;

For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call on Him;

Yet even lifeless things, either flute or harp, in producing a sound, if they do not produce a distinction in the tones, how will it be known what is played on the flute or on the harp?

a renewal in which there is no distinction between Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave and freeman, but Christ is all, and in all.
