Numbers 9:10

או בדרך רחקה [IF ANY MAN … SHALL BE UNCLEAN BY REASON OF A DEAD,] OR BE ON A DISTANT JOURNEY — There is a dot on it (on the ה of the word רחקה which letter is therefore regarded as non-existent; cf. Rashi on Genesis 18:9 and Note thereon), in order to tell that what Scripture means by בדרך רחקה is that it (the journey) need not really be a distant one, but that his sacrifice is postponed even though he was merely outside the threshold of the forecourt during the whole time that the ceremony of slaughtering the Passover sacrifice tasted. (Pesachim 93b, cf. Sifrei Bamidbar 69:2). — On the “Second Passover” one may have with him unleavened and leavened bread together in his house, and there is no festival in connection with it, and the eating of leaven is forbidden only together with it (the Passover Sacrifice) — i.e. while the sacrifice is being eaten (cf. Pesachim 95a).

דַּבֵּ֛ר אֶל־בְּנֵ֥י יִשְׂרָאֵ֖ל לֵאמֹ֑ר אִ֣ישׁ אִ֣ישׁ כִּי־יִהְיֶֽה־טָמֵ֣א ׀ לָנֶ֡פֶשׁ אוֹ֩ בְדֶ֨רֶךְ רְחֹקָ֜הׄ לָכֶ֗ם א֚וֹ לְדֹרֹ֣תֵיכֶ֔ם וְעָ֥שָׂה פֶ֖סַח לַיהֹוָֽה׃

Speak to the children of Yisra᾽el, saying, If any man of you or of your posterity shall be unclean by reason of a dead body, or be on a journey afar off, yet he shall keep the passover to the Lord.
