Why did Yakov call Rachel before Le'ah (despite the fact that he married Le'ah first and she bore him the most sons)?
Rashi: Yakov's attachment to Lavan began with Rachel, and so, from the word go, he considered her his main wife. 1
Why did Yakov leave without informing Lavan?
Seforno: Because, when he saw how Lavan had accepted the Lashon ha'Ra of his sons, he was afraid that Lavan would steal from him. 1
He later says so explicitly to him (See Bereishis 31:31).
Why did Yakov call his wives to come "to the field, to the flock"?
Tosfos ha'Shalem (1): He called them to the field, lest others hear. 1 He called them to the flock, lest he abandon his work. 2
B'rachos, 8b (quoting R. Akiva): "I love the Medes because they take counsel in the field'. 3 The Gemara attributes the source for this sound piece of advice to the current Pasuk.
Tosfos ha'Shalem (2): "Melech l'Sadeh Ne'evad" (Koheles 5:8) - counsel is taken in the field.
Even though Lavan has been deceitful for 20 years, and Yakov must flee, he works faithfully as long as he is there! (PF)
Rashi (Ibid.): Because, as the old saying goes - 'Even the walls have ears!'.
