כִּ֣י יִקָּרֵ֣א קַן־צִפּ֣וֹר ׀ לְפָנֶ֡יךָ בַּדֶּ֜רֶךְ בְּכָל־עֵ֣ץ ׀ א֣וֹ עַל־הָאָ֗רֶץ אֶפְרֹחִים֙ א֣וֹ בֵיצִ֔ים וְהָאֵ֤ם רֹבֶ֙צֶת֙ עַל־הָֽאֶפְרֹחִ֔ים א֖וֹ עַל־הַבֵּיצִ֑ים לֹא־תִקַּ֥ח הָאֵ֖ם עַל־הַבָּנִֽים׃
Apabila secara kebetulan engkau menjumpai sarang burung di jalan, di pohon apa pun atau di tanah, berisi anak-anak burung atau telur, dan induknya sedang mendekam di atas anak-anak burung atau di atas telur itu, janganlah engkau mengambil induknya selagi ia berada di atas anak-anaknya.
Rashbam
האתרים, the letter א at the beginning is similar to the letter א at the beginning of the word אפרוח or in the word אתמול, which is a variant of תמול, meaning “yesterday.” There are many occasions when the letter א serves as the beginning of a word.
Rabbeinu Yonah
And be as careful with a light commandment as with a weighty one, for you do not know the reward given [for the fulfillment] of [the respective] commandments: Even though the punishments for sins are explained to us - as some of them are with excision ( karet) and some with death at the hands of Heaven, excision being that he and his seed are cut off whereas death at the hands of Heaven is only that he is cut off, and there are some sins that get the four death penalties meted out by the court, and there are negative commandments that bring forty lashes, and the one who transgresses the rabbinic laws gets rabbinic lashes for rebellion - but the reward of the [positive] commandments is not explained to us, not for the light ones and not for the weighty ones. And the sages, may their memory be blessed, demonstrated [this with] a parable (Pesikta Rabbati 23), "To what is this similar? To a king who gave an orchard for his servants in which to plant trees. And if he made known to them the giving of reward [of the different trees], they would have all toiled on those trees that have a large reward, and it would come out that the orchard would be missing the other [trees]. So [too], were the Holy One, blessed be He, to make known the giving of reward for the [different] commandments, [people] would do the weighty ones that have a large reward and leave over the light ones that have a smaller reward, and a person would be incomplete in the commandments." And for this reason, one should not be lenient about the commandments, and his soul should hold them [all] dear to do, since he does not know which are the light ones and which are the weighty ones. But our rabbi (R. Yehuda HaNassi, the author of this mishnah) excelled in his words and gave a stronger reason than this and said that "you do not know the reward given [for the fulfillment] of [the respective] commandments" [as to] how much it is - as even the reward of a light commandment is highly elevated. And you should be careful not to lose such a great gain, like the matter that they said (Chullin 142a), "'If you chance upon the nest of a bird in front of you, etc.' (Deuteronomy 22:6) - and if for a commandment as light as a small coin the Torah says, 'in order that it will be good for you' in the world that is completely good 'and that you will have length of days' in the world that is completely long, all the more is it so for the weighty commandments of the Torah."
English Explanation of Mishnah Chullin
Which are they that are not at one's disposal? Such as geese and fowls that made their nests in the open field. But if they made their nests within a house or in the case of Herodian doves, one is not bound to let [the mother bird] go. If a bird makes its nest in the open field, then it is considered to not be at one’s disposal and one needs to send it away before taking its young. If the birds nest in the house, then when one comes to take them, he need not send the mother bird away. This is probably derived from the word “along the road” in Deuteronomy 22:6. The same is true for Herodian doves, which refers to the types of doves that Herod used to raise in his palace.
